Thrombosed Large Distal Posterior Inferior Cerebellar Artery Aneurysm Mimicking an Infratentorial Ependymoma

Large or giant intracranial aneurysms can simulate brain tumors clinically and radiologically by virtue of their progressive mass effect. Unlike aneurysms from alternative locations, those arising from the distal posterior inferior cerebellar artery (PICA) are uncommon. We report a patient who experienced progressive hemiparesis with magnetic resonance imaging findings suggestive of an infraten...

Simultaneous Vertebral Artery Dissection and Contralateral Posterior Inferior Cerebellar Artery Dissecting Aneurysm

The optimal treatment and appropriate follow-up period for an unruptured vertebral artery (VA) and/or posterior inferior cerebellar artery (PICA) dissection have not been established. Decisions regarding treatment of these vascular lesions are usually based on the manifesting symptoms and changes in radiologic findings during the follow-up period. We experienced a patient who had a simultaneous...

Aneurysm of the distal posterior inferior cerebellar artery originating from extracranial fenestrated vertebral artery.

Transoral-transclival clipping of a midline vertebral artery aneurysm.

The technical advantages and possible indications for a transoral-transclival approach for low midline posterior circulation aneurysms are discussed. A case report using such a route is described. The prognosis of untreated vertebro-basilar aneurysms is briefly discussed.
