title: Clinicopathological and radiological features of two cases of intraventricular meningioma in childhood.
abstract: The clinical, radiological and pathological features of two cases of intraventricular meningioma in a 9-year-old boy and a 9-year-old girl are reported. Presenting features included headache, vomiting and somnolence with no localizing neurological signs on physical examination. Neither patient showed evidence of neurofibromatosis. CT scans were helpful in establishing the preoperative diagnoses with uniformly hyperdense, well-circumscribed lesions showing bright enhancement after contrast within the lateral and third ventricles respectively. Histological examination revealed mixed fibroblastic/angioblastic and fibroblastic patterns, with typical electron-microscopic and immunohistochemical features of meningioma. Successful surgical removal was achieved in both cases.
