Abstract
Aneurysms of the vertebral artery are commonly found at the origin of the posterior inferior cerebellar artery (PICA). Other locations include the distal PICA and the vertebral junction. Rarely, a more proximal vertebral artery aneurysm can present in the spinal canal and lie beneath the highest denticulate ligament, which has to be transected to expose the lesion. Vertebral-PICA aneurysms usually present with subarachnoid hemorrhage, but large lesions can compress the lower cranial nerves or brain stem (Fig. 30-1).
