RESUMEN

BACKGROUND AND OBJECTIVES: Existing tools to diagnose spontaneous intracranial hypotension (SIH), namely spinal opening pressure (OP) and brain MRI, have limited sensitivity. We investigated whether evaluation of brain MRI using the Bern score, combined with calculated craniospinal elastance, would aid in diagnosing SIH and provide insight into its pathophysiology. METHODS: A retrospective chart review was performed of patients who underwent brain MRI and pressure-augmented dynamic CT myelography (dCTM) for suspicion of SIH. Two blinded neuroradiologists assigned Bern scores for each brain MRI. OP and incremental pressure changes after intrathecal saline infusion were recorded to calculate craniospinal elastance. The relationship between Bern score, OP, and elastance and whether a leak was found were analyzed. RESULTS: Seventy-two consecutive dCTMs were performed in 53 patients. Twelve CSF-venous fistulae, 2 ruptured meningeal diverticula, 2 dural defects, and 1 dural bleb were found (17/53, 32%). Among patients with imaging-proven CSF leak/fistula, OP was normal in all but 1 patient and was not significantly different in those with a leak compared with those without (15.1 vs 13.6 cm H2O, p = 0.24, A = 0.40). The average Bern score in individuals with a leak was significantly higher than that in those without (5.35 vs 1.85, p < 0.001, A = 0.85), even when excluding pachymeningeal enhancement from the score (3.77 vs 1.57, p = 0.001, A = 0.78). The average elastance in those with a leak was higher than that in those without, but this difference was not statistically significant (2.05 vs 1.20 mL/cm H2O, p = 0.19, A = 0.40). Increased elastance was significantly associated with an increased Bern score (95% CI -0.55 to 0.12, p < 0.01) and was significantly associated with venous distention, pachymeningeal enhancement, prepontine narrowing, and subdural collections, but not a narrowed mamillopontine or suprasellar distance. DISCUSSION: OP is not an effective predictor for diagnosing CSF leak and if used in isolation would result in misdiagnosis of 94% of patients in our cohort. The Bern score was associated with a higher diagnostic yield of dCTM. Elastance was significantly associated with certain components of the Bern score.

RESUMEN

BACKGROUND: Spontaneous intracranial hypotension (SIH) is a secondary cause of headache and an underdiagnosed disease. The clinical presentation can be highly variable. It typically presents with isolated classic orthostatic headache complaints, but patients can develop significant complications such as cerebral venous thrombosis (CVT). OBJECTIVE: To report 3 cases of SIH diagnosis admitted and treated in a tertiary-level neurology ward. METHODS: Review of the medical files of three patients and description of clinical and surgical outcomes. RESULTS: Three female patients with SIH with a mean age of 25.6 ± 10.0 years old. The patients had orthostatic headache, and one of them presented with somnolence and diplopia because of a CVT. Brain magnetic resonance imaging (MRI) ranges from normal findings to classic findings of SIH as pachymeningeal enhancement and downward displacement of the cerebellar tonsils. Spine MRI showed abnormal epidural fluid collections in all cases, and computed tomography (CT) myelography could determine an identifiable cerebrospinal fluid (CSF) leak in only one patient. One patient received a conservative approach, and the other two were submitted to open surgery with laminoplasty. Both of them had uneventful recovery and remission in surgery follow-up. CONCLUSION: The diagnosis and management of SIH are still a challenge in neurology practice. We highlight in the present study severe cases of incapacitating SIH, complication with CVT, and good outcomes with neurosurgical treatment.


ANTECEDENTES: Hipotensão intracraniana espontânea (HIE) é uma causa secundária de cefaleia e uma doença subdiagnosticada. A apresentação clínica pode ser muito variável. Tipicamente, se apresenta com queixas isoladas de cefaleia ortostática clássica, porém pode evoluir com complicações significativas como trombose venosa cerebral (TVC). OBJETIVO: Relatar 3 casos de diagnóstico de hipotensão intracraniana espontânea manejados em uma enfermaria de neurologia de nível terciário. MéTODOS: Revisão dos prontuários de três pacientes e descrição dos resultados clínicos e cirúrgicos. RESULTADOS: Três pacientes do sexo feminino com média de idade de 25.6 ± 10.0 anos. As pacientes apresentavam cefaleia ortostática e uma delas apresentou sonolência e diplopia devido a TVC. A ressonância magnética (RM) do encéfalo varia de achados normais até achados clássicos de HIE como realce paquimeníngeo e deslocamento inferior das tonsilas cerebelares. A RM da coluna mostrou coleções anormais de líquido epidural em todos os casos e a mielografia por tomografia computadorizada (TC) foi capaz de determinar fístula liquórica identificável em apenas uma paciente. Uma paciente recebeu abordagem conservadora e as outras duas foram submetidas a cirurgia aberta com laminoplastia. Ambas tiveram recuperação e remissão sem intercorrências no seguimento cirúrgico. CONCLUSãO: O diagnóstico e manejo da hipotensão intracraniana ainda são desafios na prática neurológica. Destacamos no presente estudo casos graves, complicação com TVC e bons resultados com tratamento neurocirúrgico.

RESUMEN

La hipotensión intracraneal espontánea (SIH) es una patología con una incidencia anual aproximada de 5 por cada 100.000 personas al año, caracterizada clásicamente por cefalea ortostática comúnmente secundaria a una fuga espontánea de líquido cefalorraquídeo (LCR), pudiendo existir a su vez una amplia gama de síntomas asociados. El diagnóstico se centra en la clínica y en hallazgos típicos en la resonancia nuclear magnética (RM), sin embargo, según diversos estudios, puede corresponder a una patología subdiagnosticada por la dificultad que ha existido en definir criterios diagnósticos universales y un manejo terapéutico estandarizado, el cual varía inicialmente entre manejo médico conservador y/o parches de sangre epidural (PHE). Reportamos el caso de una paciente femenina de 51 años quien fue atendida en el Hospital Herminda Martin de Chillán donde se realizó el diagnóstico y tratamiento sintomático con PHE.


Spontaneous intracranial hypotension (SIH) is a pathology with an annual incidence of approximately 5 per 100,000 people per year, classically characterized by orthostatic headache commonly secondary to a spontaneous cerebrospinal fluid (CSF) leak, and there may also be a wide range of of associated symptoms. The diagnosis is centered on the clinic and on typical findings in magnetic resonance imaging (MRI), however, according to various studies, it may correspond to an underdiagnosed pathology due to the difficulty that has existed in defining universal diagnostic criteria and standardized therapeutic management. which initially varies between conservative medical management and/or epidural blood patches (PHE). We report the case of a 51-year-old female patient who was treated at the Herminda Martin de Chillán Hospital where the diagnosis and symptomatic treatment with PHE were made.

RESUMEN

OBJECTIVE: To compare specific fetal cranial and cerebral findings indicative of prenatal intracranial hypotension (PICH) syndrome between open and closed cephaloceles. METHODS: Two groups of fetuses with cephalocele who underwent magnetic resonance imaging scan were selected based on the defect coverage: covered ("closed cephalocele" group, n = 4) and uncovered by skin ("open cephalocele" group, n = 8). The presence of signs associated with PICH syndrome was evaluated and findings compared between groups. RESULTS: Cases from the open cephalocele group showed statistically significant differences in comparison with the closed cephalocele group regarding reduction of the interpeduncular angle (p = 0.006), reduced amount of cerebrospinal fluid in the subarachnoid space (p = 0.01), collapsed/severely reduced fourth ventricle (p = 0.03), cephalocele content (p = 0.03), and identification of a vector traction (p = 0.03). There were no differences in the presence of cerebellar tonsillar descent, obstructive ventriculomegaly, and presence of the lemon sign. In comparison with gestational age-matched controls, only the biparietal diameter but not the head circumference was significantly smaller in both the open and closed cephalocele groups (p < 0.05). CONCLUSION: Congenital cephaloceles present distinct imaging behavior depending on the defect coverage. Therefore, the classification of cephalocele should include, in addition to location and content, the presence or absence of skin fully covering the defect.

RESUMEN

OBJECTIVE: To study the prevalence of abnormalities of the septi pellucidi (SP) in a cohort of fetuses with open spinal dysraphism (OSD) and to determine whether this condition is secondary to obstructive ventriculomegaly and, therefore, part of the natural history of prenatal intracranial hypotension (PICH) syndrome. METHODS: Magnetic resonance imaging (MRI) studies from fetuses with OSD were analyzed. The SP were assessed using axial and coronal T2-weighted images of the fetal brain and classified as intact, partially absent, or completely absent. Additionally, the correlation between the presence or absence of the SP and the size of the lateral ventricles, degree of cerebellar tonsillar herniation, collapse of the fourth ventricle, and interpeduncular angle was investigated. RESULTS: A total of 32 fetuses with OSD were studied. Mean gestational age at the time of the fetal MRI was 25.5 ± 3.9 weeks (range, 19-35) and mean ventricular size was 16.2 ± 4.2 mm (range, 8-26). Twenty-three (71.9%) fetuses had cerebellar tonsillar herniation. The IPA was completely collapsed in 23 cases (71.9%), reduced in seven (21.9%), and unreadable in two (6.3%). Twenty (62.5%) fetuses presented with intact SP, 10 (31.3%) with partially absent SP (incomplete fenestration), and two (6.3%) with completely absent SP (complete fenestration). Fenestration of the SP correlated significantly with the degree of ventriculomegaly (Pearson's correlation coefficient =0.459; p = .01). However, there was no correlation with the IPA, collapse of the fourth ventricle, and cerebellar tonsillar herniation. CONCLUSIONS: More than one-third of the fetuses with OSD had fenestration of the SP. The most probable etiology is increased intraventricular pressure leading to local necrosis of the SP. As fenestration of the SP is a secondary event associated with PICH syndrome, this condition should not be considered a contraindication for intrauterine repair of the spinal defect. Instead, it should be seen as an indicator of the severity of the intraventricular pressure.

RESUMEN

A fístula liquórica para o osso temporal constitui um evento raro que decorre da comunicação anormal entre o espaço subaracnóideo e as células da mastoide, permitindo que o líquido cefalorraquidiano flua para as porções pneumatizadas do osso temporal. Tem como consequência a hipotensão intracraniana espontânea, caracterizada por perda de líquor e pela manifestação clínica de cefaleia ortostática. Acredita-se que a hipotensão intracraniana espontânea crie condições hemodinâmicas favoráveis à ocorrência de trombose venosa cerebral, uma desordem potencialmente fatal e de difícil diagnóstico, visto a inespecificidade de sinais clínicos e sintomas. Dessa forma, é pertinente atentar para a possibilidade de trombose venosa cerebral em pacientes com fístulas liquóricas, especialmente quando houver mudança do padrão da cefaleia, que passa de ortostática a intensa e contínua.


Temporal bone cerebrospinal fluid fistula is a rare event that results from abnormal communication between the subarachnoid space and the mastoid cells, allowing the cerebrospinal fluid to flow into the pneumatized portions of the temporal bone. It leads to spontaneous intracranial hypotension, characterized by loss of cerebrospinal fluid and orthostatic headache as a clinical manifestation. Spontaneous intracranial hypotension is believed to create favorable hemodynamic conditions to the occurrence of cerebral venous thrombosis, a potentially fatal disorder of difficult diagnosis given the nonspecific clinical signs and symptoms. Therefore, it is pertinent to consider the possibility of cerebral venous thrombosis in patients with cerebrospinal fluid fistulas, especially when there is a modification in the headache pattern from orthostatic to intense and continuous pain.

RESUMEN

BACKGROUND AND OBJECTIVES: An epidural blood patch is used to treat postdural puncture and liquor hypotension headache. We report the use of an epidural blood patch in a critical pediatric patient. CASE REPORT: A 10-year-old girl with acute leukemia developed venous cerebral thrombosis with hemorrhagic transformation one month after intrathecal chemotherapy. Given the unusual clinical and imagiological evolution even after decompressive craniectomy, we suspected cerebrospinal fluid hypotension. Spine imaging revealed signs of post-lumbar puncture fistula; we hence performed a blind blood patch. CONCLUSIONS: Recognizing cerebrospinal fluid hypotension in critical pediatric patients is important. Less-conventional life-saving measures, such as a blind blood patch, may be considered in such patients.

RESUMEN

OBJECTIVE: To investigate the role of the interpeduncular angle (IPA) as a new indicator of intracranial hypotension in fetuses with open spinal dysraphism (SD). METHODS: Two groups of fetuses undergoing magnetic resonance imaging (MRI) examination were identified. The study group included fetuses with open SD (n = 21), while the control group included fetuses with a normal brain and spine (n = 43). Two observers retrospectively evaluated axial T2-weighted images of the brain and the IPA was identified and measured. Other features of the Chiari II malformation were also evaluated in the study group and correlated with the IPA. RESULTS: The average value (±SD) of the IPA for the study and control groups was 9.8° ± 18.5° and 60.2° ± 5.9°, respectively. The intergroup analysis of the IPA measurements revealed a statistically significant difference between the groups (p < 0.005). Brainstem slumping or cerebellar tonsillar descent, collapse of the fourth ventricle, and ventriculomegaly also had a significant correlation with a lower IPA (p = 0.001). CONCLUSION: Measuring the IPA may be a useful technique for assessing the degree of intracranial hypotension in fetuses with open SD. This technique can also detect less severe cases of prenatal intracranial hypotension, even before cerebellar tonsillar descent. The lower IPA in fetuses with open SD further supports the theory that cerebrospinal fluid leakage, and not traction, is the underlying cause of Chiari II malformation.

RESUMEN

INTRODUCCIÓN: El síndrome de Marfán es un trastorno multisistémico del tejido conectivo de herencia autosómica dominante, de expresión variable. La ectasia dural es un compromiso frecuente, pero poco conocido, que puede asociarse a síndrome de hipotensión endocraneana (SHE). OBJETIVO: Pre sentar un caso de cefalea invalidante secundario a SHE, para advertir de esta rara complicación, que debe tenerse presente en niños portadores de conectivopatías, en especial síndrome de Marfán. CASO CLÍNICO: Adolescente femenina de 13 años, portadora de sindrome de Marfán, de diagnóstico clínico según criterios de Ghent 2010, que consultó por cefalea ortostatica invalidante de 6 meses de evolución. La Resonancia Magnetica (RM) de cerebro mostró múltiples signos de hipotensión endocraneana, mientras que la RM de columna total mostró una ectasia dural que determinó la dilatación del saco tecal y remodelación posterior de los cuerpos vertebrales, especialmente a nivel del sacro. Se realizó tratamiento con parche sanguíneo autólogo epidural con buena respuesta clínica. CONCLUSIONES: La ectasia dural, frecuente en el sindrome de Marfán, es una causa predisponente a fuga de líquido cefaloraquideo (LCR), que podría causar cefalea ortostática segundaria al SHE.


INTRODUCTION: Marfan syndrome is an autosomal dominant, multi-systemic connective tissue di sorder of different presentations. Dural ectasia is a common, but little known complication that can be associated with intracranial hypotension syndrome (IHS). OBJECTIVE: To present a case of severe headache secondary to IHS in order to warn about this rare complication, which must be considered in children carriers of connective tissue diseases, especially Marfan syndrome. CLINICAL CASE: 13-year- old female carrier of Marfan syndrome, clinically diagnosed according to the 2010 Ghent criteria, who consulted due to a 6-months history of severe orthostatic headache. Head magnetic resonance imaging (MRI) showed multiple signs of intracranial hypotension, while whole-spine MRI showed dural ectasia that caused the thecal sac dilation and subsequent remodeling of vertebral bodies, es pecially the sacral ones. Treatment with an autologous epidural blood patch was administered with good clinical response. CONCLUSIONS: Dural ectasia, frequent in Marfan syndrome, is a predisposing cause of cerebrospinal fluid (CSF) leakage, which could cause orthostatic headache secondary to IHS.

RESUMEN

Spontaneous intracranial hypotension (SIH) is a rare neurological condition caused by low cerebrospinal fluid (CSF) volume, most commonly due to a CSF leak. The most common presenting symptom is an orthostatic headache, but some patients may present with atypical neurological manifestations such as cranial nerve palsies, an altered mental status, and movement disorders, which complicate the clinical diagnosis. Therefore, the diagnosis is based on the combination of clinical signs and symptoms, neuroimaging, and/or a low cerebrospinal fluid pressure. In this review, we describe the wide variety of neurological manifestations and complications seen in patients with SIH as well as the most common features described on imaging studies, including both subjective and objective measurements, in order to lead the clinician to a correct diagnosis. The prompt and correct management of patients with SIH will help prevent the development of life-threatening complications, such as subdural hematomas, cerebral venous thrombosis, and coma, and avoid unnecessary invasive procedures.

RESUMEN

Spontaneous intracranial hypotension (SIH) is a syndrome that was unknown until the advent of magnetic resonance imaging (MRI). It is a cause of orthostatic headache, which remains underdiagnosed and, rarely, can result in several complications including dural venous sinus thrombosis, subdural hematoma and subarachnoid hemorrhage. Some of these complications are potentially life-threatening and should be recognized promptly, mainly by imaging studies. We reviewed the MRI of nine patients with SIH and describe the complications observed in three of these patients. Two of them had subdural hematoma and one had a dural venous sinus thrombosis detected by computed tomography and MRI. We concluded that MRI findings are of great importance in the diagnosis of SIH and its complications, which often influence the clinical-surgical treatment of the patient.

RESUMO Hipotensão Intracraniana Espontânea (HIE) é uma síndrome desconhecida até o advento das imagens de Ressonância Magnética (RM). É uma causa de cefaleia ortostática que permanece subdiagnosticada e raramente resulta em complicações, como trombose de seios venosos durais, hematoma subdural e hemorragia subaracnoidea. Algumas dessas complicações são potencialmente ameaçadoras à vida e devem ser prontamente reconhecidas pelos estudos de imagem. Nós revisamos as RM de 9 pacientes com HIE e descrevemos as complicações observadas em 3 casos. Dois deles tiveram hematoma subdural e um teve trombose de seio venoso dural detectados por tomografia computadorizada e RM. Concluímos que achados de RM são de grande importância no diagnóstico de HIE e suas complicações, frequentemente influenciando o tratamento clínico-cirúrgico do paciente.

RESUMEN

Introducción: Las fístulas de líquido cefalorraquídeo (LCR) constituyen una complicación frecuente de la cirugía espinal. La cisternografíaradioisotópica es una herramienta diagnóstica que permite la confirmación y localización de las mismas.Caso clínico: Paciente masculino de 30 años, con antecedentes de hidrocefalia congénita y a quien se le retiró hace ocho años un sistema derivativo lumboperitoneal colocado por esa causa. Consultó por episodios de cefalea ortostática de aproximadamente seismeses de evolución y que se aliviaban con el decúbito. Al realizarle la punción lumbar, para el estudio del LCR, se comprobó una presión de apertura de 5 cm H2O y los estudios citoquímicos, bacteriológicos, micológicos y virológicos fueron negativos. Se le realizó una cisternografía radioisotópica con 99Tc-DTPA que mostró una fístula de LCR en el sitio donde fue retirado el catéter de derivación lumboperitoneal.Conclusión: La cisternografía radioisotópica es una opción práctica y eficaz para corroborar el diagnóstico de fístula de LCR como complicación de la cirugía espinal en pacientes con hipotensión intracraneal(AU)


Introduction: Cerebrospinal fluid (CSF) fistulas are a common complication of spinal surgery. The radioisotope cisternography is a diagnostic tool that allows confirmation and localization.Case report: Male patient of 30 years, with a history of congenital hydrocephalus and eight years ago was removed a derivative lumboperitoneal shunt system placed by that cause. Consulted by episodes of approximately six months of orthostatic headache with relief in decubitus. A lumbar puncture was done for the study of CSF, an opening pressure of 5 cm H2O, and cytochemical, bacteriological,mycological and virological studies were negative. A cisternography radioisotope 99Tc-DTPA was done and showed a CSF fistula on the site where the lumboperitoneal shunt catheter was removed.Conclusion: The radioisotope cisternography is a practical and effective option to confirm the diagnosis CSF fistula as a complication ofspinal surgery in patients with intracranial hypotension(AU)

RESUMEN

Intracraneal hypotension headache is a well known syndrome in neurosurgery practice. In most cases cerebrospinal fluid leaks are caused by medical interventions, such as lumbar puncture, peridural anesthesia and surgical interventions on the spine. Clinical symptoms tipically show orthostatic headache that resolves in supine position, and other symptoms like neck tightness, vertigo and diplopia. RMI diagnostic confirms paquimeningeal enhancement and subdural hygromas. Conservative treatment usually includes bed resting, hydratation and administration of caffeine or glucocorticoids, resolving spontaneously in one to four months. The importance of the diagnosis lies in the differential diagnosis with other causes of headache, as symptomatic limiting factor in the rehabilitation of the patient and the same favorable prognosis.

RESUMEN

OBJETIVO: Determinar los factores asociados a la mortalidad de los pacientes con traumatismo craneoencefálico grave en la unidad de cuidados intensivos del Hospital Nacional Daniel A. Carrión. MATERIAL Y METODOS: El tipo de estudio es descriptivo, observacional, retrospectivo, analítico, correlacional. La población fue los pacientes admitidos en la UCI con diagnóstico de Traumatismo craneoencefálico grave durante el periodo enero 2010 a diciembre 2012 que cumplan los criterios de ingreso. Se consideró 36 pacientes que cumplen los criterios de inclusión y exclusión. RESULTADOS: El 33.3 por ciento del total de pacientes con TECG tienen una edad de 25 a 35 años. La media de edad es 36 años. El 88.9 por ciento del total de pacientes con TECG son hombres y el 72.2 por ciento del total de pacientes con TECG son causadas por accidentes de tránsito. El 63.9 por ciento del total de pacientes con TECG presentan puntuación en la escala de Glasgow de 6 a 8; el 36.1 por ciento presentan hipotensión: el 30.6 por ciento presentan hipoxemia al ingreso; el 41.7 por ciento presentan Marshall CT III; el 47.2 por ciento tienen hiperglicemia; el 38.9 por ciento presentan midriasis bilateral al ingreso; el 30.6 por ciento presentó coagulopatía: el 66.7 por ciento fueron sometidos a neurocirugía de emergencia; la mortalidad es de 36.1 por ciento. Del total de paciente TECG que fallecieron el 23.1 por ciento tienen edad de 25 a 35 años o 55 a 65 años se encontró relación estadística P<0.05, el 92.3 por ciento son de sexo masculino, y del total de fallecidos el 61.5 por ciento fueron causa por accidentes de tránsito se encontró relación estadística P<0.05. Del total de paciente TECG que fallecieron el 69.2 por ciento tienen puntuación en la escala de Glasgow de 3 a 5, se encontró relación estadística P<0.05, asimismo se aprecia que el 61.5 por ciento presentan hipotensión se encontró relación estadística P<0.05, el 69.2 por ciento presentan Hipoxemia al ingreso se encontró relación...


OBJECTIVE: This research aims to determine established associated factors with mortality in patients with severe head trauma in the intensive care unit of the National Hospital Daniel A. Carrion. MATERIAL AND METHODS: The type of study is descriptive, retrospective observational, analytical, and correlational. Patients admitted to the ICU with a diagnosis of severe head trauma during the period January 2010 to December 2012 that met the entry criteria. 36 patients fulfilling the inclusion and exclusion criteria were considered. RESULTS: 33.3 per cent of all patients have TSCG age 12 to 25 years; 33.3 per cent of all patients have TSCG age 25 to 35 years. The average age is 36 years old. 88.9 per cent of all patients with TSCG are men and 72.2 per cent of all patients with TSCG are caused by traffic accidents. 63.9 per cent of patients presented TSCG ranking scale of 6-8 Glasgow; 36.1 per cent have hypotension; 30.6 per cent have hypoxemia at admission; 41.7 per cent have CT Marshall III; 47.2 per cent had hyperglycemia; 38.9 per cent with bilateral mydriasis on admission; 30.6 per cent developed coagulopathy; 66.7 per cent underwent surgery; mortality is 36.1 per cent of total patient who died TSCG. 23.1 per cent are aged 25 to 35 or 55 to 65 years with a statistical relationship P<0.05 was found, the 92.3 per cent were male, and total 61.5 per cent of deaths were caused by traffic accidents, statistical relationship P<0.05. From all patient who died was found that 69.2 per cent had a GCS of 3 to 5, with a statistical relationship P<0.05, also shows that 61.5 per cent have hypotension statistical relationship P<0.05 was found, 69.2 per cent have hypoxemia at admission statistical relationship P<0.05 was found; 46.2 per cent have Marshall CT NELM statistical relationship P<0.05 was found, 69.2 per cent presented with hyperglycemia, statistical relationship P<0.05 was found; of all deaths 76.9 per cent presented with bilateral mydriasis P<0.05 was found...
