Lateral ventricular meningioma.
A 47-year-old woman presented with a 6-month history of progressive dizzy spells and occasional impairment of vision. Cranial computerized tomographic (CT) scan showed a calcified mass in the atrium of the left lateral ventricle, densely enhanced after intravenous administration of contrast material. Left carotid and vertebral angiograms demonstrated that the feeders of the tumor were coming from the left anterior choroidal and left lateral posterior choroidal arteries, both of which showed dilatation and neovascularity. The CT and angiographic findings led to successful removal of the tumor without impairment of the patient's vision. The pathological diagnosis was meningioma.
