Spontaneous intraventricular hemorrhage caused by lateral ventricular meningioma--case report.
A 39-year-old female presented with acute intraventricular hemorrhage manifesting as sudden onset of headache associated with gradually progressing somnolence and left oculomotor nerve paresis. Intraventricular hemorrhage occurred from a meningioma of the lateral ventricle. Computed tomography and magnetic resonance (MR) imaging revealed intraventricular hemorrhage and a mass in the right trigone. The tumor was totally removed. Her postoperative course was uneventful except for left homonymous hemianopia. The histological diagnosis was fibroblastic meningioma. The MR imaging was highly suggestive of hemorrhage from the tumor periphery.
