A 42-year-old man was found in a comatose state, and computed tomography scans disclosed a massive intraventricular hemorrhage. Continuous ventricular drainage was carried out as an emergency measure. However, the patient died about 22 hours after the onset. At autopsy, a tangle of vessels in the glomus chorioideum and a dilated, tortuous vein on the surface of the choroid plexus were found in the left lateral ventricle. Microscopic examination of the glomus chorioideum revealed an angioma composed of arteries and veins of varying size and thickness on both sides.
Choroid plexus angioma is uncommon and most often occurs in children and adolescents. Bilateral lesions have been reported in only five cases. Because of the potential for intraventricular hemorrhage and the tendency for recurrence, surgical removal of angiomas is recommended.
