Thrombosed Giant Posterior Communicating Aneurysm Simulating Brain Neoplasm: A Case Report

ABSTRACT

A giant intracranial aneurysm(GIA) is an aneurysm greater than 2.5cm in size. GIA may simulate brain tumor on computed tomography scans. We report a case of giant thrombosed posterior communicating artery aneurysm simulating brain tumor. To minimize brain retraction and achieve excellent exposure in the shortest possible distance during the operation, we used a new surgical technique, an orbitozygomatic infratemporal approach, with good results.
