Pediatric Intraventricular Meningioma: Radiopathological Study and Review of the Literature

Abstract

Pediatrics intraventricular meningiomas are rare poor prognosis tumors with reported incidence of 0.5-5% of all meningiomas. Presentation is in the form of raised ICP ; therefore the definite diagnosis is based on neuroimaging studies and histopathology. These tumors pose a huge surgical challenge for neurosurgeons due to its deep location and risk of intraoperative massive blood loss. Here we describe the case of a 5-year-old boy presented with 2 months of progressive headaches associated with nausea and unsteadiness. Fundoscopy showed bilateral papilloedema. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed large solid intraventricular mass within the left lateral ventricle. On histology and immunohistochemistry, a diagnosis of intraventricular meningioma was made. Postoperatively the patient did not received chemotherapy or radiotherapy and he was doing well after 18 months follow-up and disease free on clinical and radiological examination.
