Dissecting aneurysms of the posterior cerebral artery: angioarchitecture and a review of the literature.
Isolated dissecting aneurysms of the posterior cerebral artery are not as rare as previously reported. Affecting primarily a younger population, this condition can be recognized by angiographic patterns, the most common being a "pearl and string" morphology. We reviewed the literature and present a series of six cases, discussing management strategies.
