Advances in microneurosurgical treatment of arterial aneurysm have led to increased interest being focused on aneurysm situated within the posterior cerebral fossa. Despite this, reports of neurosurgical intervention in such cases are still rare and there is no report about the distal posterior cerebral artery aneurysm in Korea. An aneurysm of the posterior cerebral artery has been referred to as a "distinct rarity", making up about 0.26 to 2.7% of all cerebral aneurysms. Especially, the incidence of the distal posterior cerebral artery aneurysm is quite rare and most of them are saccular in shape and single in number. The authors report a case of P4 segment aneurysm of left posterior cerebral artery, successfully treated by clipping cross neck and reviewed the literature, and discussed their anatomy, clinical feature, location, and variable operative methods.
Key Words: Distal posterior cerebral artery; P4 segment Interhemispheric approach; Transcortical approach
