title: An unusual intraventricular haemangiopericytoma: MRI and spectroscopy.
abstract: We present a 43-year-old woman with a tumour within the left lateral ventricle with the typical appearances of meningioma on MRI. (1)H MR spectroscopy demonstrated an increased choline peak, suggesting a malignant form of meningioma. Histologically a haemangiopericytoma was found, an exceptionally rare tumour at this site.
