We describe the case of a 60-year-old man who presented with a giant dissecting aneurysm of the left P2 segment. Intracranial dissecting aneurysms often occur in the vertebrobasilar system, but rarely involve the posterior cerebral artery (PCA). PCA aneurysms tend to have some peculiar features and therefore may be considered a separate entity, even from the vertebrobasilar aneurysms. The patient was treated by endovascular occlusion of both parent vessel and the aneurysm, and he tolerated the procedure well with a complete resolution of clinical deficit, following volume reduction of the aneurysm. This paper presents additional evidence to literature reports suggesting that endovascular parent artery occlusion with coils is an effective and well-tolerated treatment for distal PCA aneurysms. Our review contributes to collect data regarding the incidence of recurrence as a measure of long-term efficacy of this therapeutic approach.
