ABSTRACT
Resumen Los meningiomas son los tumores primarios más frecuentes del sistema nervioso central, tienden a ser benignos y de lento crecimiento. Pueden ser asintomáticos o incluso manifestarse únicamente con síntomas psiquiátricos, incluyendo un cuadro psicótico. No existen estudios clínicos controlados randomizados que estudien la relación entre meningioma y cuadros psicóticos. La evidencia disponible se basa en series y reportes de casos. Existe una relación entre la magnitud del edema perilesional y la presencia de síntomas psicóticos. Por otra parte, el tamaño de la lesión o su localización neuroanatómica específica tendrían menor relevancia. La resección quirúrgica de la lesión, en conjunto con el manejo psiquiátrico adecuado, usualmente conduce al cese de la sintomatología psicótica. En la evaluación de pacientes con síntomas psicóticos se debe tener un elevado índice de sospecha, en particular en cuadros de reciente inicio, con manifestaciones atípicas o resistentes al tratamiento. En estos casos se recomienda un estudio con neuroimágenes. Este artículo presenta el caso de una paciente evaluada en nuestro hospital diagnosticada con un meningioma frontal izquierdo de gran tamaño, que presentó sintomatología psicótica secundaria, y se expone una revisión bibliográfica actualizada de esta asociación.
Meningiomas are the most frequent central nervous primary tumors, which tend to be benign and present a slow growth. They may be asymptomatic or present clinically just with psychiatric symptoms including a psychotic state. There are no clinical randomized controlled trials that study the relationship between meningioma and a psychotic episode. Available evidence is based on case reports and series. There is a relationship between the magnitude of perilesional edema and the presence of psychotic symptoms. On the other hand, the size of the tumor or its specific neuroanatomic location would have less relevance. Surgical resection of the tumor associated with psychiatric management usually leads to the cessation of psychotic symptoms. In the assessment of patients with psychotic symptoms, there must be a high index of suspicion, particularly in first psychotic episodes, atypical manifestations and resistance to treatment. In these cases, a neuroimaging study is recommended. This article presents the case of a patient evaluated in our hospital and diagnosed with a large left frontal meningioma with secondary psychotic symptoms, and an updated bibliographic review of this association is presented.

Background Predominantly intraosseous meningiomas are rare entities that include true primary intraosseous meningiomas (PIM), as well as meningiomas that may show extensive bone involvement, such as en plaque meningiomas. Different hypotheses have been proposed to decipher the origin of PIMs, such as ectopic arachnoid cap cell entrapment during birth or after trauma. Surgical resection is the treatment of choice of such lesions. Case presentation We present a case of a 65-year-old man with an enlarging mass in the parieto-occipital region that grew slowly and progressively over 13 years, following head trauma during a motor vehicle accident. One year prior to presentation, he started experiencing daily holocranial headaches and blurry vision. CT and MRI studies revealed a permeative midline calvarial lesion measuring 14 cm in greatest dimension with extensive periosteal reaction, extension into the subcutaneous soft tissues, subjacent dural thickening and intracranial extension with invasion of the superior sagittal sinus. The favored pre-operative clinical diagnosis was osteosarcoma. The abnormal calvarium was excised and histopathological examination confirmed the diagnosis of a predominantly intraosseous calvarial meningioma, WHO grade I. Conclusions The present case highlights the importance of histopathologic diagnosis in guiding therapeutic decisions and reiterates the necessity of considering PIM or meningiomas with extensive intraosseous component in the differential diagnosis of calvarial masses, even when imaging suggests a neoplasm with aggressive behavior, such as osteosarcoma.

Meningiomas são os principais tumores primários do sistema nervoso central (SNC) que afetam cães e gatos. Na maioria dos casos, são neoplasias benignas, geralmente expansivas, causando compressão do SNC, e raramente fazem metástase para outros órgãos. O presente trabalho tem como objetivo relatar a ocorrência de um meningioma microcístico com metástase pulmonar em um canino de 11 anos de idade, com sinais clínicos de andar cambaleante, compressão da cabeça contra objetos, agitação, salivação e agressividade. Na necropsia, foram observadas, no encéfalo, massas bem delimitadas pardo-avermelhadas, firmes, de aspecto granular, localizadas no córtex parietal e nos núcleos da base. Inúmeras micronodulações de aspecto semelhante foram observadas no pulmão. Histologicamente observaram-se nódulos formados por células neoplásicas fusiformes, com núcleos grandes e alongados e nucléolos evidentes, dispostas de forma frouxa, formando vacúolos e microcistos. À imuno-histoquímica, o meningioma apresentou marcação fortemente positiva para citoqueratina e negativa para vimentina. Por meio da histopatologia e da imuno-histoquímica, foi possível estabelecer a classificação histológica de meningioma microcístico, bem como diferenciá-lo de outras doenças que cursam com sinais nervosos.(AU)
Meningiomas are the main tumors of the central nervous system (CNS) affecting dogs and cats. In most of the cases they are benign neoplasms, usually expansive, causing compression of the CNS and rarely metastasize to other organs. We describe the occurrence of a microcystic meningioma with pulmonary metastasis in an 11 - year - old canine with clinical signs of staggering gait, head compression against objects, agitation, salivation and aggressiveness. At necropsy, well-defined, firm, granular-looking masses located in the parietal cortex and nuclei of the base were observed in the encephalon. Numerous micronodulations of similar appearance were observed in the lung. Histologically, nodules formed by spindle neoplastic cells with large, elongated nuclei and evident nuclei were loosely arranged, forming vacuoles and microcysts. Immunohistochemistry were strongly positive for cytokeratin and negative for vimentin. Through the histopathology and immunohistochemistry, it was possible to establish the histological classification of microcystic meningioma, as well as to differentiate from other diseases that present with nervous signals.(AU)

En el período comprendido entre el 1ero de enero de 2017 al 1ero de enero del 2019. Los 15 pacientes intervenidos conformaron el universo de estudio. Resultados: la media poblacional fue de 55 años. Predominó el sexo femenino en un 73,3 %. La cefalea fue la manifestación clínica más frecuente, igualmente, que los meningiomas de la convexidad cerebral. En cuanto a la topografía, la media del tamaño de la lesión fue de 4,4 cm. La variedad meningotelial (40 %) fue la que predominó. El grado II de resección fue el que más se empleó. El edema cerebral postquirúrgico predominó en un 26,6 %. La puntuación de la escala de Karnofsky al egreso fue superior que al ingreso. Conclusiones: cuanto más precoz se realice el diagnóstico clínico y tratamiento quirúrgico en los pacientes portadores de meningioma, mejor será su calidad de vida al egreso (AU).
ABSTRACT Introduction: meningiomas are the second cause of primary brain tumors in adults, representing up to 32 % of the total. Objective: to describe the behavior of intracranial meningioma in the studied patients. Materials and methods: a retrospective, descriptive, analytical study was conducted on neurosurgery patients with intracranial meningioma in the Neurosurgery service of the University Teaching Hospital "Comandante Faustino Pérez Hernández" of the province of Matanzas, in the period from January 1st 2017 to January 1st, 2019. The 15 patients undergoing neurosurgery were the study universe. Results: the population mean was 55 years; female sex prevailed (73.3 %). Headache was the most frequent clinical manifestation as well as meningiomas of cerebral convexity in terms of topography. The average lesion size was 4.4 cm; the meningothelial variety (40 %) was the most commonly found; grade II resection was the most used one. Post-surgical cerebral edema (26.6%) predominated. Karnofsky scale score at discharge was higher than at admission. Conclusions: the earlier the clinical diagnosis and surgical treatment are performed in patients with meningioma the better will be their quality of life at discharge (AU).

Foramen magnum (FM) tumors represent one of the most complex cases for the neurosurgeon, due to their location in a very anatomically complex region surrounded by the brainstem and the lower cranial nerves, by bony elements of the craniocervical junction, and by the vertebrobasilar vessels. Currently, the open approach of choice is a lateral extension of the posteriormidline approach including far lateral, and extremelateral routes. However, the transoraltranspharyngeal approach remains the treatment of choice in cases of diseases affecting the craniocervical junction. For very selective cases, the endoscopic endonasal route to this region is another option.We present a case of a ventral FM meningioma treated exclusively with the endoscopic endonasal approach.

Los meningiomas clinoideos son tumores benignos originados en la leptomeninges que rodea el proceso clinoideo anterior, representando el 17 por ciento de los basales. Con el objetivo de caracterizarlos se estudiaron los pacientes operados en el Servicio de Neurocirugía del Hospital Hermanos Ameijeiras (2000 al 2010). La serie estuvo integrada por 10 pacientes, 9 mujeres y un hombre, la edad promedio fue de 49,8 años, clínicamente caracterizados por cefalea (10 pacientes) y déficit de la agudeza visual (9 pacientes). A todos se les practicó un abordaje frontotemporal-orbitozigomático (FTOZ) alcanzándose 7 resecciones totales y 3 subtotales, 3 pacientes sufrieron complicaciones, al alta ocho de los diez operados egresaron en excelente estado, no tuvimos recidiva ni recrecimiento tumoral en los casos con resecciones parciales y al año de seguimiento la calidad de vida según la escala de Karnofsky fue superior o igual a 80 puntos en todos los casos. Concluimos que los meningiomas clinoideos por su asiento en el centro de la base craneal relacionados anatómicamente con estructuras neurovasculares críticas y por las grandes dimensiones que alcanzan en el momento de su diagnóstico, representan un desafío en la práctica neuroquirúrgica, comportándose en nuestra serie más frecuentes entre las mujeres con la cefalea y el déficit visual monocular como síntomas principales. Las técnicas de base de cráneo y en nuestras manos la craneotomía FTOZ complementadas con osteotomías basales de diferentes grados, han demostrado ser una alternativa eficaz para mejorar la suficiencia de la resección tumoral con mínima morbilidad, ausencia de recurrencias y mortalidad.
Clinoidal meningeomas are benign tumors originated in the liptomeningeo surrounding the anterior clinoidal process representing 17 percent of basal tumors. With the objective to characterize it, studied were patients operated in the neurosurgical service of Hermanos Ameijeiras hospital from 2000 to 2010.The series were composed of 10 patients, 9 female and a male, the mean age was 49.8 years and were clinically characterized with headache (10 patients) and visual deficit (9 patients). To all were practiced a frontotemporal orbitozygomatic approach (FTOZ) reaching 7 total and 3 subtotal removal,3 patients suffered complications, 8 out of 10 patients operated were discharged in good condition. There was no recurrence after total removal and after a year of fellow up, the life quality following Karnofsky scale was superior o equal to 80 points in all the cases. In conclusion Clinoidal meningeomas due to its placement in the cranial base with anatomical relations with critical neurovascular structures and also the great dimension to reach in the moment of its diagnosis represents a challenge to neurosurgical practice. It comports in our series with more frequency within females presenting headache and mono ocular visual defect as the principal symptoms. Craneal base techniques and in our case frontotemporal-orbitozygomatic craniotomy complimented with basal osteotomy of different grades, had demonstrated to be an efficient alternative to better the technique of total removal with less mobility, zero recurrence and mortality.

Multiple endocrine neoplasia type 1 (MEN1) syndrome includes varying combinations of endocrine and non-endocrine tumors. There are also a considerable number of atypical MEN1 syndrome. In this case, a 68-yr-old woman was referred to the Department of Endocrinology for hypercalcemia. Five years ago, she had diagnosed as primary hyperaldosteronism and now newly diagnosed as parathyroid hyperplasia with laboratory and pathologic findings. Hurthle-cell thyroid cancer was also resected during the parathyroid exploration and small meningioma was found on brain MRI. Her general condition has markedly improved and her adrenal mass and meningioma are being closely observed now. We could find the loss of heterozygosity of the MEN1 locus in parathyroid glands, suggesting a MEN1-related tumor, but not a germline mutation. Considering a variety of phenotypic expression and a limitation of current molecular analysis, periodic follow up will be needed in patients with a MEN1-like phenotype.

Mantle cell lymphoma (MCL) is an uncommon type of gastrointestinal lymphoma. MCL is a distinct subtype of B-cell non-Hodgkin lymphomas. The major subtype of MCL is characterized by the presence of multiple lymphomatous polyposis (MLP), in which multiple polyps are observed along the gastrointestinal tract. The malignant cells express pan B-cell marker and the T-cell marker cluster of differentiation 5. The chromosomal translocation t(11;14)(q13;q32) that causes cyclin D1 overexpression is commonly observed on the cytogenetic analysis of MCL. Survival improvement has recently been achieved for patient with MCL by the successful introduction of monoclonal antibodies and dose-intensified approaches for treatment, including autologous stem cell transplantation strategies. Some reports suggest that there is an increased incidence of second malignancies in patients with MCL or lymphoma. We report a case of MCL involving the colon; the patient was a 60-year-old man who complained of low abdominal discomfort during defecation. During the workup, a meningioma was unexpectedly discovered. On analysis, the tumor was found to be a t(11;14)-negative and non-MLP-type MCL.

Background: Intraventricular meningiomas are rare tumors and pose clinical, radiological, and surgical challenges. Individualized approach helps to establish successful results. Methods: Thirteen patients underwent craniotomy for intraventricular meningioma resection from 1999 to 2007. The mean age was 45 years (23-64), time of presentation between 25 days to three years. There were ten females and three males. Headaches and seizures were the most frequent initial presentations. Tumors were located in the ventricular trigone in 11 patients and in the temporal horn in two. Results: There were seven posterior temporal and seven parieto-occipital transcortical craniotomies, one patient was operated two times. Resection grade was Simpson I in nine patients, Simpson II in four, and Simpson III in one case. Surgical mortality was zero. There were six complications. Two patients had ventriculitis, one patient had hematoma of the surgical bed, one patient had severe post-operative cognitive impairment and one presented with progression of motor deficits. In two patients, there was transient memory disturbance after the parieto-occipital approach. Conclusion: Correct understanding of microsurgical anatomy cooperates for further success in operation of intraventricular meningiomas. Pre-operative embolization is helpful to reduce bleeding when a suitable tumor feeder can be accessed with no reflux. Dynamic changes in the shape of the ventricular cavity have to be considered when planning the most suitable route. Rigorous hemostasis and ventricular drainage are important points to avoid main complication.

Relatamos o caso de uma mulher de 65 anos de idade, com queixa de cefaleia, portadora de uma lesão expansiva em região posterior da tenda do cerebelo, implantado na tórcula, sugestivo de meningioma pelos exames de imagens, foi submetida ao tratamento neurocirúrgico para ressecção. Ao exame anatomopatológico, foi sugerido diagnóstico de doença de Rosai-Dorfman, confirmado pela imunohistoquímica. Trata-se de uma rara linfadenopatia proliferativa histiocítica, de comportamento benigno, com acometimento mais frequente da cadeia linfonodal cervical e outros sítios extranodais, sendo extremamente rara sua localização no sistema nervoso central, principalmente na fossa posterior, sem acometimento de outras estruturas anatômicas.
We report the case of a woman 65 years old, complaining of headache, carries a lesion in the posterior region of the tent of the cerebellum, implanted in torcula, suggestive of meningioma by imaging tests, was subjected to neurosurgical procedures for resection. When pathological examination suggested a diagnosis of Rosai-Dorfman disease, confirmed by immunohistochemistry. It is a rare proliferative histiocytic lymphadenopathy in benign behavior, with more frequent involvement of cervical lymph node and other extranodal sites, its location is extremely rare in the central nervous system, especially in the posterior fossa without involvement of other anatomical structures.

Occurrence of peritumoral brain edema (PBE) in meningiomas has been associated with several factors in recent years, although its pathophysiological mechanism has not yet been fully elucidated. The aim of this study was to analyze the correlation between the presence / degree of PBE and factors such as gender, age, size and histological subtype of tumor. We analyzed the MRI images of 74 patients operated on Hospital Beneficência Portuguesa de Porto Alegre for the presence / degree of PBE and data was statistically correlated with the parameters of the patient. PBE was present in 70.1 percent of patients. Tumors with higher volume had more PBE. Tumors of the olfactory groove showed more PBE than sphenoid wing and parassagittal tumors. Transitional subtype showed more PBE than fibroblastic and meningothelial subtypes.
A presença de edema cerebral peritumoral (ECP) em meningiomas tem sido associada a diversos fatores nos últimos anos, embora o seu mecanismo fisiopatológico ainda não tenha sido inteiramente elucidado. O objetivo desse estudo foi analisar a correlação entre a presença/grau de ECP e fatores como sexo, idade, volume e subtipo histológico do tumor. Foram analisadas imagens de RM de 74 pacientes operados no Hospital Beneficência Portuguesa de Porto Alegre quanto à presença/grau de ECP e os dados correlacionados estatisticamente com os parâmetros do paciente. ECP estava presente em 70,1 por cento dos pacientes. Tumores com maior volume apresentaram mais ECP. Tumores da goteira olfatória apresentaram mais ECP que os da asa do esfenóide e que os parassagitais. Meningiomas transicionais apresentaram mais ECP que os fibroblásticos e que os meningoteliais.

To study the functional outcome after surgical excision of cortical meningio-angiomatosis [MA] in terms of seizure control and neurological disability. Four patients with MA were diagnosed with refractory epilepsy. All were surgically treated. Four cases of MA were reported three males and one female. Median age at presentation was 19 years [range 9-23 years]. All patients had refractory seizures for 1-18 years with a median of 8 years. Two patients had exclusively simple partial seizures, with secondary generalization; the other two patients had complex partial seizures, with secondary generalization. CT and MRI were done for all patients. The lesion was in the right frontal lobe in one patient, left frontal in one patient, left tempropolar in one patient and right temporal in one patient. After surgical resection, three patients remained seizure free without antiepileptic treatment and the fourth patient became controlled on monotherapy of antiepileptic treatment. No patients had added neurological deficit in the postoperative follow-up period of six months to eight years [mean 4.7 years] MA commonly presents as refractory epilepsy. Although MA occurs infrequently, it is important to establish the correct diagnosis. Surgical excision is usually associated with good functional outcome with the patients either stop the antiepileptic treatment or become controlled on smaller doses
