Association of a dolichoectatic middle cerebral artery and an intracranial cavernous hemangioma--case report.
A normotensive, non-smoking 41-year-old female with a history of generalized seizures from the age of 4 years presented with a left middle cerebral artery (MCA) fusiform aneurysm and an ipsilateral frontal lobe cavernous hemangioma. Surgical exploration demonstrated that the fusiform aneurysm-like lesion was a dolichoectatic MCA with no arteriosclerotic change. The pathogenesis of dolichoectasia is obscure, but the association of a dolichoectatic MCA and an intracranial cavernous hemangioma is suggestive of congenital factors.
