title: Case report: intraventricular meningioma with cerebellopontine angle and drop metastases.
abstract: A 34-year-old Chinese woman underwent successful gross total excision of a benign fibroblastic meningioma, pre-operatively diagnosed by computed tomography (CT), arising from the left lateral ventricle of the brain. After a quiescent period of 5 years, CT and magnetic resonance imaging (MRI) demonstrated tumour recurrence at the same site. Despite two further excisions of progressively malignant intraventricular meningiomas and treatment with radiotherapy, the patient rapidly developed bilateral cerebellopontine angle and spinal drop metastases. CT and MRI were useful in demonstrating the location and extent of recurrent intraventricular meningiomas, as well as metastatic spread via the cerebrospinal fluid.
