Trigonal Cavernous Hemangioma: Case Report

Cavernous hemangiomas are typically located in the subcortical areas, deep white matters and basal ganglia. They are rarely seen in the intraventricular or extraaxial spaces. Trigonal hemangioma has been reported even less frequently. A 3-month-old boy presented with a history of severe hydrocephalus with sun-set eyes, dyspnea, cyanosis, and fast eye movement. The magnetic resonance images (MRI) of the brain revealed a heterogeneously enhancing mass with hemorrhage located in the trigone of lateral ventricle and extending into the left temporal area. The patient underwent total removal without any perioperative event. Histological examination demonstrated a hemangioma, predominantly cavernous type. We report a case of cavernous hemangioma in the trigone of lateral ventricle who presented with distinct features comparing to other.prohibitio
