“…5,6 The frequency of intraventricular meningiomas in children is 12%, whereas it ranges from 0.5% to 4.5% in adults. 7 Intraventricular meningiomas most often develop in the trigone of the lateral ventricles, with an unexplained predilection for the left lateral ventricle. Approximately 15% arise in the third ventricle, which is more common in childhood, and only about 5% arise in the fourth ventricle.…”

Childhood meningiomas are rare and display important differences from adult forms. We report the first case of an intraventricular metaplastic meningioma arising in a child. A 7-year-old female underwent resection of an enhancing tumor arising within the left lateral ventricle. It was composed of monomorphic cells embedded within an abundant myxoid stroma. The cells demonstrated epithelial membrane antigen and vimentin immunoreactivity. Ultrastructural analysis demonstrated intermediate filaments, complex intercellular interdigitations and desmosomes, and a diagnosis of myxoid (metaplastic) meningioma was rendered. This case reflects the higher incidence of intraventricular meningiomas in childhood and greater incidence of intraventricular meningiomas in the left lateral ventricle. Recognition of the grade I myxoid meningioma in this case is paramount since chordoid meningiomas, which share similar histologic features, are of a higher grade and worse prognosis.

“…The long term prognosis for surgically treated menigiomas in children is controvertial, but according to the conclusion from the most recent and largest review about intracranial meningiomas in children, made by Caroli et al in 2006 33 , who colleted 440 cases reported in the literature, children like adults, with typical meningiomas and complete resections show good outcome.…”

-Meningiomas are uncommon tumors in children and either more rarely encountered in the pineal region. We report two cases of meningioma of the pineal region in children. One of these cases was a five years-old girl and the other a one year-old boy. No specific clinical presentation or tomographic examinations findings was identified before treatment, suggestive of a diagnosis of menigioma. The clinical and laboratory features were very similar to the most common tumors of the pineal region. Prior to the surgery, the histology of these tumors was not suspected. Both patients underwent direct surgery and complete removal was achieved by a suboccipital transtentorial approach. The tumors originated from velum interpositum in both cases. At the follow up, one case presented with recurrence six years later, and she underwent a reoperation with total resection without morbidity. Long-term follow up presented no other recurrences.KEY WORDS: meningiomas, meningeal neoplams, pineal tumors, velum interpositum, falcotentorial junction, children. Meningiomas da região da pineal em criançasRESUMO -Meningiomas são tumores poucos frequentes em crianças, e mais raramente encontrados na região da pineal. Relatamos dois casos de meningioma da região da pineal em crianças, uma menina de cinco anos e um menino de um ano de idade. Não foi identificada nenhuma forma de apresentação clinica ou caracteristica tomográfica, antes do tratamento, que sugerisse o diagnóstico de meningioma. As características clinicas e laboratoriais encontradas foram similares às de tumores mais frequentes da região da pineal. Ambos os pacientes foram submetidos ao tratamento cirúrgico e a remoção completa foi obtida por abordagem suboccipital transtentorial. Durante o seguimento, um dos pacientes foi reoperado por recorrencia do tumor seis anos após o tratamento inicial. Atualmente, os pacientes encontram-se livres de recorrência tumoral.PALAVRAS-CHAVE: meningioma, neoplasia meningea, velum interpositum, junção falcotentorial, crianças.

E-mail: neurosp@uol.com.brLiterature specifically concerning to meningioma of the pineal region in children is scarce. Meningiomas are relatively common tumors in adults and account for approximately 20% of all intracranial tumors 1 . Their incidence ranges from 1.1% to 4.2% of all intracranial tumor in pediatric age and in this corresponds to a proportion varying from 2,8% to 5,9% of meningiomas in all ages 2, 3 . Meningiomas in children predominate during the second decade and are extremely uncommon in infancy. In children, meningiomas appear in unusual sites and usually reach enormous sizes, and locations that are rare in adults 2,3 . Meningiomas in the pineal region may originate either from the velum interpositum or from the falcotentorial junction.We are describing our experience with two cases of meningiomas in the pineal region in children arising within the velum interpositum, with no dural attachment. Lack of dural...

“…In our series, we found that the average duration of symptoms with hemangiopericytoma was 4.0 months, whereas in pediatric patients, the average duration with meningioma was 1.2 years. 18 Besides intracranial meningioma, the following tumors should be differentiated. 1) Glioblastoma.…”

SUMMARY:Intracranial meningeal hemangiopericytomas in children and adolescents are prone to bleeding during surgery. CT and MR imaging may serve a role in preoperative diagnosis. The purpose of this report was to describe the radiologic findings in 9 pathologically proved cases of intracranial meningeal hemangiopericytomas in children and adolescents. The average duration of symptoms was short (mean, 4.0 months; median, 1.5 months). The intraoperative blood loss was large (mean, 3561 mL; median, 1000 mL). Tumors were extra-axial, irregularly multilobular, and hypervascular. Radiologically, they showed mixed attenuation on precontrast CT images, heterogeneous signal intensity on precontrast MR imaging, and marked and heterogeneous enhancement on postcontrast MR imaging. Bone erosion was sometimes present, but hyperostosis was not present. On MR imaging, multiple signal intensity voids of vessels were observed in 100% (8/8) of tumors with AVM-like signal intensity flow voids in 25% (2/8) of tumors. These results suggest that CT and MR imaging findings may be helpful for preoperative diagnosis.
