Intraventricular Meningioma: Case Report and Literature Review

Abstract

In this article we describe the clinical course of a child with an intraventricular meningioma and review the relevant literature. A 7-year-old girl with a several-month history of headaches had a CT scan that demonstrated a large, enhancing, intraventricular tumor. The tumor was completely excised via a superior parietal approach. Pathological examination revealed a pleomorphic meningioma. Postoperative scans demonstrated no residual tumor. Pediatric intraventricular tumors are rare. The surgical objective is complete resection, which appears to be associated with excellent outcomes.

Giant pediatric intraventricular meningioma: Case report and review of literature

“…[1] This is much less as compared to adults where they are about 30% of the total, of which only 3%–4% are intraventricular. [3] In children, however, a much larger proportion (10%–15%) are intraventricular and usually occur in the trigone of the lateral ventricles. [3] In another sharp contrast with the adults, meningiomas in the pediatric population are more common in males.…”

[3] In another sharp contrast with the adults, meningiomas in the pediatric population are more common in males. [14] This is probably due to the absence of effect of sex hormone on steroid receptors.…”

“…A significantly higher proportion (up to 40%) of these tumors is associated with neurofibromatosis. [23] The patients with neurofibromatosis are more likely to present with multiple tumors. [2] Prior radiation exposure, especially in cases of childhood, leukemia has been reported to predispose to development of meningiomas.…”

Giant Atypical Intraventricular Meningioma in a Child

“…These tumors are often associated with neurofibromatosis type II [5]. Intraventricular meningiomas are thought to arise from the arachnoidal cap cells that were trapped within the choroid plexus, the velum interpositum or the tela choroidea, thus the lateral ventricle is the most common location [6]. Meningiomas of the 3rd or 4th ventricle are exceptionally rare [1].…”
