Síndrome de Currarino incompleto. Presentación de un caso

El síndrome de Currarino es una enfermedad hereditaria y de baja incidencia, compuesta por una tríada: estenosis anal, malformación sacro coccígea y masa presacra. Puede cursar desapercibido hasta la adultez y generar subdiagnósticos. Se describe un paciente de 75 años, masculino, piel negra, de procedencia urbana y con antecedentes de hipertensión arterial, quien acudió al hospital por presentar hematuria, dolor en fosa lumbar izquierda y estreñimiento. Se realizaron estudios imagenológicos, como ultrasonido, tomografía de abdomen y resonancia magnética lumbosacra, los cuales condujeron al diagnóstico de tumor renal, síndrome de Currarino incompleto (dado por dos elementos de la triada: malformación sacro coccígea y masa presacra) asociado a otra enfermedad malformativa raquimedular, médula anclada. Son pocos los casos reportados en el mundo (casi 300), por lo que se considera una entidad rara, pero de fácil diagnóstico debido al advenimiento de las nuevas tecnologías en el campo de la imagenología.

Currarino syndrome is a hereditary disease with a low incidence, composed of a triad: anal stenosis, sacrococcygeal malformation and presacral mass. It can go unnoticed until adulthood and generate subdiagnoses. A 75-years-old male, black-skinned, urban origin patient with a history of arterial hypertension is described, who attended the hospital presenting hematuria, pain in the left lumbar fossa, and constipation. Radiological studies such as ultrasound, abdominal tomography and lumbosacral magnetic resonance were performed, which led to the diagnosis of a renal tumor, incomplete Currarino syndrome (given by two elements of the triad: sacrococcygeal malformation and presacral mass) associated with another spinal cord malformation disease, tethered cord. There are few cases reported in the world (almost 300), so it is considered a rare entity, but easy to diagnose due to new imaging technologies.

The First Case of Fetus in Fetu in Nicaragua: The Management Experience of the Pediatric Neurosurgery Team.

Fetus in fetu (FIF) is a rare congenital anomaly of asymmetric monozygotic twins, where the parasitic twin develops abnormally inside the body of the host twin. In most cases, it is incorporated into the sibling's abdomen, which frequently presents as a retroperitoneal mass. Currently, at least 200 cases have been reported worldwide, being this the first case in Nicaragua. We describe a case of a male newborn, born via cesarean section, with a history of multiple congenital malformations observed via ultrasound examination. At birth, a mass is observed on its dorsum that impresses a skull, but without the presence of bones, with three limbs, two upper and one lower, with an outline located transversely on the pelvic girdle and the presence of two male genitalia with agenesis of the testicles and an accessory kidney. A preoperative diagnosis of FIF and spinal dysraphism was made by computed tomography (CT) and magnetic resonance imaging (MRI). They shared a spinal cord and had the presence of an open spinal defect type meningocele with aberrant roots. After the diagnosis and discussion, the multidisciplinary team proceeded to surgery to perform the separation of the twin (FIF). The subsequent anatomopathological examination revealed that the fetus was anencephalic and had reliable FIF characteristics. The resection was performed followed by the closure of the 430 mL meningocele and complete separation of the spine and the parasitic twin. We present the first case of fetus in fetu in Nicaragua.

Giant anterior sacral meningocele associated with hydroureteronephrosis and renal injury: illustrative case.

BACKGROUND: Anterior sacral meningocele (ASM) is a defect in the closure of the neural tube. Patients can be asymptomatic or present with genitourinary, neurological, reproductive, or colorectal dysfunction. Magnetic resonance imaging (MRI) is the gold standard test because it can assess communication between the spinal subarachnoid space and the lesion and identify other abnormalities. Surgical correction is the definitive treatment because untreated cases have a mortality rate of more than 30%. OBSERVATIONS: A 24-year-old woman with Marfan syndrome presented with polyuria, recurrent urinary tract infections, and renal injury for 3 months along with a globose abdomen, with a palpable mass in the middle and lower third of the abdomen that was massive on percussion. MRI showed an ASM consisting of two cystic lesions measuring 15.4 × 14.3 × 15.8 and 6.7 × 6.1 × 5.9 cm, respectively, compressing the distal third of the right ureter and causing a hydroureteronephrosis. Drainage and ligature of the cystic lesion were performed. The urinary outcome was excellent, with full recovery after surgery. LESSONS: ASM should be suspected in all abdominal masses with progressive symptoms in the setting of Marfan syndrome. Computed tomography and MRI are important to investigate genitourinary anomalies or other types of dysraphism to guide the best surgical approach.

Changes in Spina Bifida Lesion Level after Folic Acid Fortification in the US.

OBJECTIVE: To assess whether the severity of cases of spina bifida changed after the institution of mandatory folic acid fortification in the US. STUDY DESIGN: Six active population-based birth defects programs provided data on cases of spina bifida for 1992-1996 (prefortification period) and 1999-2016 (postfortification period). The programs contributed varying years of data. Case information included both a medical record verbatim text description of the spina bifida diagnosis and spina bifida codes (International Classification of Diseases, Clinical Modification, or a modified birth defects surveillance coding system). Comparing the prefortification and postfortification periods, aORs for case severity (upper-level lesions [cervical, thoracic] vs lower-level lesions [lumbar, sacral]) and prevalence ratios (PRs) were estimated. RESULTS: A total of 2593 cases of spina bifida (out of 7 816 062 live births) met the inclusion criteria, including 573 cases from the prefortification period and 2020 cases from the postfortification period. Case severity decreased by 70% (aOR, 0.30; 95% CI, 0.26-0.35) between the fortification periods. The decrease was most pronounced for non-Hispanic White mothers. Overall spina bifida prevalence declined by 23% (PR, 0.77; 95% CI, 0.71-0.85), with similar reductions seen across the early, mid, and recent postfortification periods. A statistically significant decrease in upper-level lesions occurred in the postfortification period compared with the prefortification period (PR, 0.28; 95% CI, 0.22-0.34), whereas the prevalence of lower-level lesions remained relatively similar (PR, 0.94; 95% CI, 0.84-1.05). CONCLUSIONS: The severity of spina bifida cases decreased after mandatory folic acid fortification in the US. Further examination is warranted to better understand the potential effect of folic acid on spina bifida severity.

Occipital encephalocele associated with Dandy-Walker malformation: a case-based review.

INTRODUCTION: Occipital encephalocele is a brain malformation that has been remotely associated with Dandy-Walker; only case reports and very small series have been published so far; therefore, their behavior and management are still under investigation. The goal of the present case-based review is to provide a summary of the state of the art in this association. METHODS AND RESULTS: The pertinent literature has been reviewed, and an exemplary case has been reported (an 11-month-old female with Dandy-Walker malformation and occipital encephalocele). So far, 33 cases have been described, with a mean age at surgery of 5, 1 day). The majority of the cases tend to present with hydrocephalus. There are no specific surgery approaches or global consensus about this association. The management possibly relies on surgery with shunt or encephalocele excision but without a dedicated protocol yet. CONCLUSIONS: The clinical research on occipital encephalocele in association with Dandy-Walker malformation is just at the beginning. New targets and wide-ranging clinical trials are needed to get an optimal management protocol.

Recursos fisioterapêuticos nas disfunções miccionais em injúrias espinhais congênitas / Physiotherapeutic resources in voiding dysfunctions in congenital spinal injuries

Malformações congênitas são alterações morfológicas com origem no desenvolvimento embrionário e podem ser devido a causas genéticas, ambientais ou ambas. Em indivíduos que sofrem de injúrias espinhais congênitas, a bexiga neurogênica (BN) é um dos acometimentos com maior impacto na vida diária e o principal objetivo urológico é melhorar o manejo urinário e a continência social, para diminuir altas pressões vesicais e prevenir danos renais. Esta condição reflete diversas repercussões, como a diminuição na qualidade de vida, progressão para procedimentos invasivos, lesão renal e ao óbito. Objetivo: Revisar sistematicamente os estudos publicados nos últimos 10 anos a respeito da atuação da fisioterapia na incontinência urinária (IU) nas injúrias espinhais congênitas. Métodos: Revisão sistemática de literatura realizada através de busca, entre os anos de 2009 a 2019, nas bases de dados eletrônicas PubMed, Bireme e PEDro. Resultados: Não houve grande conformidade em relação às técnicas utilizadas, mas sim em relação aos desfechos analisados, sendo verificado estudos sobre IU na espinha bífida. Conclusão: A fisioterapia mostrou-se benéfica para os casos de IU nas injúrias espinhais congênitas, melhorando os parâmetros urodinâmicos e o desfecho no diário miccional. (AU)

Congenital malformations are morphological changes originating from embryonic development and can be due to genetic, environmental or both. In individuals suffering from congenital spinal injuries, the neurogenic bladder (BN) is one of the disorders with the greatest impact on daily life and the main urological objective is to improve urinary management and social continence, to decrease high bladder pressures and prevent kidney damage. This condition reflects several repercussions, such as a decrease in quality of life, progression to invasive procedures, kidney injury and death. Objective: To systematically review the studies published in the last 10 years regarding the role of physical therapy in urinary incontinence (UI) in congenital spinal injuries. Methods: Systematic literature, between the years 2009 to 2019, in the electronic databases Pubmed, Bireme and PEDro. Results: There was no great conformity in relation to the techniques used, but in relation to the analyzed outcomes, with studies on UI in spina bifida being verified. Conclusion: Physical therapy proved to be beneficial for cases of UI in congenital spinal injuries, improving urodynamic parameters and the outcome in the voiding diary. (AU)

Prenatal diagnosis of closed spina bifida: multicenter case series and review of the literature.

Objective: Closed spina bifida (CSB) is an abnormality of the posterior arch formation in which the defect is covered by the skin, without protrusion of nervous tissue. The prenatal diagnosis of CSB is very difficult, rarely diagnosed antenatally.Methods: We present a multicenter case series of six prenatal diagnosis of CSB using two-dimensional (2D) ultrasonography complemented with three-dimensional (3D) ultrasonography and magnetic resonance imaging (MRI). All cases of prenatal diagnosis of CSB were confirmed in the postnatal period/termination of pregnancy by both clinical and/or imaging diagnosis (ultrasonography and MRI).Results: 2D ultrasonography allowed the prenatal diagnosis of six cases. We observed two cases of subcutaneous lipomas, two cases of meningoceles, one case of fibrolipomas, and one case of false-positive CSB (meningomyelocele). 3D ultrasonography using rendering mode was important in one case of meningocele (case# 3). Three cases were delivered at term and one of them was submitted to corrective surgery. All these three newborns were discharged from the hospital well and without neurologic signs. Termination of pregnancy was performed in three cases.Conclusion: During prenatal evaluation, detailed ultrasonographic assessment of the entire spine with the identification of the position and morphology of the conus medullaris and absence of cranial signs of spinal dysraphism are the most valuable sonographic clues for the diagnostic of the CSB.

Mature intracranial teratoma with meningocele in a lamb / Teratoma intracraniano benigno com meningocele em um cordeiro

ABSTRACT: This study described the pathological aspects of a mature intracranial teratoma with meningocele in a one-day-old lamb. The diagnosis of mature teratoma was based on microscopic features, where well-differentiated tissues representative of the three germ layers were observed. The tumor consisted of respiratory, gastrointestinal and urinary epithelium as components of the endoderm; muscle and bone tissues as components of the mesoderm; and keratinized stratified squamous epithelium and adnexa as components of the ectoderm. To the best of our knowledge, this is the first report of intracranial teratoma with meningocele in animals.

RESUMO: Descrevem-se os aspectos patológicos de um teratoma intracraniano benigno com meningocele em um cordeiro de um dia de idade. O diagnóstico de teratoma benigno foi baseado nos achados histopatológicos, com tecidos representativos das três camadas germinativas. O tumor consistia de epitélio respiratório, gastrintestinal e urinário como componentes do endoderma; tecido muscular e ósseo do mesoderma; e epitélio escamoso estratificado queratinizado e anexos como componentes do ectoderma. Com base no conhecimento dos autores, este é o primeiro relato de teratoma intracraniano com meningocele em animais.

Perfil epidemiológico de mortalidade por espinha bífida / Epidemiological profile of mortality from Spina Bifida

Objetivo: Avaliar o perfil epidemiológico nacional de mortalidade por espinha bífida. Métodos: Trata-se de estudo observacional, descritivo, de série temporal, a partir de dados obtidos da plataforma eletrônica do Departamento de Informática do Sistema Único de Saúde entre os anos de 2005 e 2015. Resultados: Nesse período, as proporções de óbitos infantis relacionados à espinha bífida diminuíram. As Regiões Sul e Sudeste mantiveramse abaixo da média nacional, e as demais permaneceram acima, corroborando o maior apoio técnico nas regiões consideradas referências em saúde no país. As maiores diminuições proporcionais nos coeficientes de mortalidade infantil ocorreram no Nordeste e no Centro-Oeste, de 351,55 a 155,56 e de 809,52 a 290,32, respectivamente. Isso pôde ser justificado por essas duas regiões apresentarem maiores proporções de óbitos. Conclusão: Com a atenuação de outras causas de mortalidade infantil, as malformações evidenciaram-se. O acompanhamento pré-natal, a adoção de estilo de vida saudável pelas gestantes e a prevenção dos fatores de risco para defeitos de fechamento do tubo neural, sobretudo pela suplementação com ácido fólico, merecem destaque na redução do número de óbitos infantis e na perpetuação da vida.

Objective: To evaluate the national epidemiological profile of mortality from Spina Bifida. Methods: This is an observational, descriptive study of a time series, based on data obtained from the electronic platform of the Department of Informatics of the Unified Health System (DATASUS) between 2005 and 2015. Results: In this period, the proportions of infantile deaths related to spina bifida decreased. The Southern and Southeastern regions remained below the national average, while the others remained above, resulting in a greater technical support from the regions considered health references in the country. The largest proportional decreases in infant mortality coefficients took place in the Northeast and Midwest, from 351.55 to 155.56, and from 809.52 to 290.32, respectively. This can be justified by the fact that these two regions have higher proportions of deaths. Conclusion: Because of the attenuation of other causes of infant mortality, the malformations were evidenced. Prenatal follow-up, the adoption of a healthy lifestyle by pregnant women, and the prevention of risk factors for neural tube defects, especially through folic acid supplementation, shall be highlighted for the reduction in the number of infant deaths, and for perpetuation of life

Quiste aracnoideo sacro recidivante con meningocele anterior gigante: reporte de caso / Sacral arachnoid recurrent cyst with giant anterior meningocele: a case report

Los quistes aracnoideos corresponden a lesiones benignas expansivas del canal medular secundarias a defectos anatómicos durales, mientras que los meningoceles anteriores consisten en la herniación de la duramadre hacia la pelvis a través de forámenes dilatados o defectos óseos. Ambas entidades son infrecuentes y sus manifestaciones clínicas puede variar de acuerdo a estructuras anatómicas que comprimen. Una historia clínica completa, la pesquisa diagnóstica y la adecuada interpretación de imágenes orientan al diagnóstico y manejo de estos pacientes. Se presenta el caso de una paciente adulta mayor con historia de masa pélvica, dolor lumbar severo y monoparesia en quien se realizó el diagnóstico incidental de quiste aracnoideo sacro y meningioma sacro anterior.

Arachnoid cysts are benign expansive lesions of the spinal canal secondary to dural defects, whereas the anterior meningoceles consist of the herniation of the dura into the pelvis through dilated foramina or bone defects. Both pathologies are infrequent and its clinical manifestations vary according to compressed anatomical structures. A complete clinical history, the diagnostic investigation and the correct imaging studies interpretation guide the diagnosis and management of these patients. We present the case of an elderly adult patient with a history of pelvic mass, severe lumbar pain and monoparesis in whom the incidental diagnosis of sacral arachnoid cyst and anterior sacral meningioma was performed.

Transpalatine Route for the Correction of Transsphenoidal Encephalocele in a Child: A Case Report and Literature Review

Introduction Transsphenoidal encephalocele is a rare neural tube defect characterized by the herniation of meninges and eventually of parts of the brain through a bony defect in the sphenoid bone. The clinical presentation is variable, and surgical treatment is controversial. Case Report This report describes the case of an 8-month-old female child diagnosed with transsphenoidal encephalocele. The child presented with obstruction of the upper airways and was fed via a nasogastric tube but did not present changes in the hypothalamic-pituitary-axis. The patient underwent surgery with the transsphenoidal­transpalatine route, with an excellent outcome and without fistulas or infections. Conclusions Although transsphenoidal encephalocele is a rare congenital anomaly, the transsphenoidal­transpalatine route for the correction of this type of encephalocele is a safe option and produces a favorable outcome in pediatric patients.

Introdução A encefalocele transesfenoidal é um defeito do tubo neural raro, caracterizado por herniação de meninges e eventualmente partes do cérebro através de uma falha óssea no osso esfenoide. A apresentação clínica é variável e o tratamento cirúrgico é controverso. Relato de Caso No presente trabalho descrevemos o caso de uma criança de 8 meses, sexo feminino, com diagnóstico de encefalocele transesfenoidal. Apresentava-se com obstrução de vias aéreas superiores, alimentando-se por sonda nasoenteral e sem alterações do eixo hipotálamo-hipofisário. Tratada com cirurgia via transesfenoidal transpalatal, evoluiu com excelente resultado, sem fístulas e sem infecções. Conclusões Embora a encefalocele transesfonoidal seja uma anomalia congênita rara, a via transpalatina-transesfenoidal para correção deste tipo de encefalocele é uma opção segura e produz um resultado favorável no paciente pediátrico.

Síndrome de Currarino como enfermedad infrecuente dentro del diagnóstico diferencial de la patología anexial oncológica / Currarino Syndrome as a Rare Disease in the Differential Diagnosis of Oncological Adnexal Pathology

El Síndrome de Currarino se define como la presencia de una tríada característica que asocia: estenosis anal, malformación sacrococcígea y masa presacra. La escasa sintomatología, caracterizada además por su inespecificidad, provoca que en muchas ocasiones el diagnóstico se realice durante la edad adulta y pueda confundirse con patologías ginecológicas, de origen predominantemente oncológico. El diagnóstico mediante pruebas de imagen, se realiza fundamentalmente a través de la resonancia magnética nuclear. La extirpación quirúrgica de la masa presacra unida al tratamiento sintomático del resto de la triada son la base terapéutica de esta infrecuente patología. Presentamos el caso de una paciente de 20 años de edad con estreñimiento crónico y dolor abdominal inespecífico. Es enviada al Servicio de Ginecología por la presencia de una masa de gran tamaño que se supone de origen anexial. Tras el estudio exhaustivo de dicha paciente, se llegó a la conclusión diagnóstica de que dicha tumoración corresponde a un meningocele, asociado a agenesia parcial sacra y estenosis anal; tríada que define al Síndrome de Currarino.

Currarino Syndrome is defined as the presence of a characteristic triad that associates anal stricture, sacrococcygeal malformation and presacral mass defines this syndrome. The scarce symptomology, also characterized by nonspecific symptoms, conditions that in many cases the diagnosis is made in adulthood and can be confused with gynecological pathologies. The diagnosis is made by imaging tests, fundamentally the NMR (nuclear magnetic resonance). The main treatment is the surgical excision of the mass presacra together with the symptomatic treatment of the rest of symptoms. We present the case of a 20-year-old patient with chronic constipation and abdominal pain that is referred to Gynecology due to the presence of a mass that is supposed to be adnexal. After the study of this patient is diagnosed a meningocele, associated with partial sacral agenesis and anal stricture, triad that defines Currarino Syndrome.

Meningocele sacro anterior que simula quiste de ovario tabicado / Anterior sacral meningocele simulating ovarian cyst baffled

El meningocele sacro anterior es una rara anomalía genética asociada a enfermedades del tejido conectivo como el síndrome de Marfán, síndrome de Loeys-Dietz, la neurofibromatosis tipo 1 y otras. El objetivo del presente trabajo es presentar el caso de un feto con meningocele sacro anterior, inicialmente diagnosticado como un gran quiste de ovario multilobulado, en una paciente con diagnóstico de síndrome de Marfan. Se trata de una herniación del saco dural, a través de agujeros sacros amplios y deformados por ectasia dural, ocupada mayormente por líquido cefalorraquídeo. La punción de estas estructuras o su rotura en el acto operatorio se ha asociado a complicaciones graves e incluso la muerte(AU)

The anterior sacral meningocele is a rare genetic anomaly associated with connective tissue diseases such as Marfan syndrome, Loeys-Dietz syndrome, neurofibromatosis type 1 and others. The aim of this paper is to present the case of a fetus with anterior sacral meningocele, initially diagnosed as a large multilobulated ovarian cyst in a patient diagnosed with Marfan syndrome It is a herniation of the dural sac, through large sacral foramina, and deformed by dural ectasia, occupying mostly by cerebrospinal fluid. Puncture or rupture these structures during surgery has been associated with serious complications and even death(AU)

Nasoethmoidal meningocele in a child presenting bilateral congenital cystic adenomatoid malformation: Evidence for a new entity or consequence of gestational exposures?

BACKGROUND: Nasoethmoidal meningocele is considered an uncommon type of cephalocele, and congenital cystic adenomatoid malformation (CCAM) is a rare lung disorder characterized by overgrowth of the terminal bronchioles. CASE: We report the unusual association between a nasoethmoidal meningocele and CCAM type II in a fetus exposed to valproic acid and misoprostol. The mother was an 18-year-old woman on her first pregnancy. She had a history of absence seizures since she was 5 years old. She took valproic acid from the beginning of the gestation until the end of the third month. At the end of the third month, she attempted interruption of her pregnancy using misoprostol. The fetal nasoethmoidal meningocele and CCAM type II were identified through morphological ultrasound examination and magnetic resonance imaging. A genome-wide study detected one copy number variation classified as rare, entirely contained into the SPATA5 gene. However, it does not seem to be associated to the clinical findings of the patient. CONCLUSION: To our knowledge, there is only one case reported in the literature showing the same association between a nasoethmoidal meningocele and CCAM. Thus, the malformations observed in our patient may be related to the gestational exposures. Also, we cannot rule out that the patient may present the same condition characterized by a cephalocele and CCAM described by some authors, or even an undescribed entity, because some hallmark features, such as laryngeal atresia and limb defects, were not observed in our case. Further reports will be very important to better understand the associations described in our study.

Meningocele sacro anterior y estreñimiento / Anterior sacral meningocele and constipation

Se presenta el caso clínico de una mujer de 25 años con estreñimiento crónico en quien inicialmente se confundió el diagnóstico con enfermedad ginecológica versus tumor pélvico; en laparotomía exploratoria se evidencia lesión quística dependiente del sacro en su cara anterior por lo que se recurre a toma de imágenes diagnósticas con tomografía computarizada donde se observa meningocele sacro anterior, y posteriormente resonancia magnética para descartar otras lesiones asociada. Se plantea manejo quirúrgico con abordaje posterior para resección de cele y laminectomía con buenos resultados postoperatorios. En control de los 3 meses se encuentra paciente sin déficit neurológico, sin pérdida de sensibilidad en región perineal ni alteraciones de su sistema nervioso vegetativo.

A case is presented of a 25 year-old woman with chronic constipation in whom the diagnosis was initially confused with a gynaecological disease or a tumour. The exploratory laparotomy showed evidence of a cystic lesion hanging from the anterior side of the sacrum. Diagnostic imaging with computed tomography was performed in which an anterior sacral meningocele was observed. Magnetic resonance was then used to rule out any other associated lesions. It was decided to treat it surgically with a posterior approach for resection and laminectomy of the meningocele, with a good post-surgical outcome. In the follow-up at 3 months the patient showed no neurological deficit, no loss of sensitivity in the perineal region, and no changes in her autonomic nervous system.

Malformación del cordón espinal hendido con expresión clínica en el período neonatal / Split spinal cord malformation seen at the neonatal stage

La malformación del cordón espinal hendido es una forma rara de disrafia espinal oculta, se reporta que representa el 3 % de los disrafismos ocultos. El mayor porcentaje de ellos es de localización lumbar. En la literatura cubana solo tenemos referencia de 2 pacientes publicados, una adulta y otro caso pediátrico. Se reporta un recién nacido remitido a nuestro centro por presentar meningocele occipital. Se detecta la presencia de una fosita en región sacro-coccígea, hipotonía muscular en miembro inferior derecho, pie varo con poca movilización del miembro, e incontinencia de esfínter vesical y anal. Los estudios de imagen demuestran la presencia de 2 hemimédulas a nivel lumbar, por lo que se confirma que el recién nacido presenta un síndrome de malformación del cordón espinal hendido, una entidad poco común. Presenta, además, la particularidad de haber sido diagnosticada en el período neonatal por exhibir desde su nacimiento manifestaciones clínicas, como consecuencia de esta entidad, aspecto también relevante, pues, habitualmente, la afección expresa la sintomatología más tarde en la vida, o se mantiene asintomática.

Split spinal cord malformation is a rare form of occult spinal dysraphia and is reported in 3 % of occult dysraphisms which are mainly located in the lumbar region. The Cuban literature made reference to two patients with this condition, an adult and a child. This is the case of a male newborn referred to our center because he presented with occipital meningocele. The examination revealed a small fossa in the sacrococcygeal region, muscular hypotonic in his right lower limb, varus foot and little movement as well as anal and vessical sphincter incontinence. Imaging studies show the presence of two hemicords at the lumbar region, so it is confirmed that this newborn infant had split spinal cord malformation syndrome, which is an uncommon entity. It is interesting to note that this malformation was diagnosed at the neonatal phase because of its clinical manifestations, a relevant aspect since this illness generally shows its symptoms in later life or remains asymptomatic.

Tumoração retro-orbitária sugestiva de meningocele da bainha do nervo óptico / Retro-orbital tumor suggestive of optic nerve sheath meningocele

Meningocele da bainha do nervo óptico é uma condição extremamente rara, com poucos casos relatados na literatura. Exames de imagem revelam alargamento tubular-cístico do nervo óptico, com espessamento do mesmo. Os sintomas são muitas vezes relacionados com o comprometimento do nervo, ocasionando diminuição de lenta a acelerada da acuidade visual. O tratamento cirúrgico precoce por meio da descompressão da bainha do nervo óptico pode proporcionar melhora da função visual. Apresenta-se um caso de paciente com as características clínicas e radiológicas desta condição patológica rara. Paciente masculino, atendido no serviço com queixa de proptose do olho direito (OD) desde nascimento, com progressão nos últimos meses associada à dor. Melhor acuidade visual corrigida de conta dedos a 50 cm do OD. Olho esquerdo sem anormalidades. Ressonância Magnética de OD demonstrou formação expansiva cística de limites definidos em situação intraconal em órbita direita, em íntima relação com nervo óptico, determinando compressão, deformidade e deslocamento anterior do bulbo ocular, além de apresentar sinal semelhante ao líquor em todas as sequências obtidas. Suscitou-se hipótese diagnóstica de meningocele da bainha do nervo óptico direito e o paciente foi encaminhado para cirurgia descompressiva.

Meningocele of the optic nerve sheath is an extremely rare condition with a few cases reported in literature. Image studies reveal tubularcystic enlargement of the optic nerve although with the same thickness. Symptoms are often related to the involvement of the optic nerve, leading from slow to accelerated decreasing of the visual acuity. The early surgical treatment is the decompression of the optic nerve sheath, which it could provide improvement of visual function. We are presenting a case report of a patient who showed clinical and radiological signs of this rare pathological condition. Male patient attended at service complaining of proptosis of right eye (OD) since birth, in progress during the last months associated to stabbing pain.
