Abstract

A 49-year-old man presented with right basal ganglia hemorrhage due to a ruptured distal lenticulostriate artery aneurysm associated with ipsilateral occlusion of M1 segment of middle cerebral artery with moyamoya-type vessels. Conservative treatment was initially selected. However, the patient suddenly became drowsy with left hemiparesis due to recurrent bleeding 14 days after admission, and excision of the aneurysm was urgently performed via right frontotemporal craniotomy. The follow-up angiography showed successful resolution of the aneurysm. This report describes a rare case of a distal lenticulostriate artery aneurysm associated with ipsilateral middle cerebral artery occlusion with moyamoya-type vessels, which resulted in intracerebral hemorrhage on the right basal ganglia and intraventricular hemorrhage.
