A Large Aneurysm at Peripheral Middle Cerebral Artery in Juvenile Patient

A Case Report

Abstract

We report a case of a large aneurysm originating from a peripheral middle cerebral artery. A 27-year-old man, who was admitted for a minor head injury, had an asymptomatic peripheral aneurysm of the left middle cerebral artery. He had no history of congenital heart disease, systemic infectious disease, or severe head injury.
On intraoperative inspection the aneurysm was a fusiform type and had a smooth and thick wall, which suggested that the aneurysm was congenital in origin. The aneurysm was treated with dome clipping.
We discuss the origin and treatment of peripheral middle cerebral artery aneurysms with a review of literature and emphasize the usefulness of 3D-CT angiography.
