Fungal Aneurysm

Abstract

Abstract We report a 58-year-old woman with acromegaly whose invasive adenoma was treated by trans-sphenoidal removal and radiation. Six months after therapy, she experienced progressive headache and retro-orbital pain. At 10 months she developed unilateral blindness, mild proptosis, opthalmoplegia. and trigeminal sensory loss. Studies failed to show an expanding mass lesion. About 1 year after her operation, she suddenly became comatose and died. An autopsy examination revealed subarachnoid hemorrhage from a ruptured fungal aneurysm of the basilar artery. The literature on such aneurysms is reviewed.
