[Extracranial aneurysm of the posterior inferior cerebellar artery. A case report].
A case is presented of an aneurysm arising in an extracranial loop of the left posterior inferior cerebellar artery (P.I.C.A.). Two similar cases can be found in a review of the literature. It is essential to obtain clear visualization of both P.I.C.A.s. in the evaluation of patients with subarachnoid hemorrhage. Surgical treatment of this aneurysm, located distal to the lateral medullary segment, involves a midline approach with retraction or subpial resection of the tonsillar tip.
