Giant and multiple aneurysms of the distal posterior inferior cerebellar artery

Abstract

A case involving giant and multiple aneurysms of the distal posterior inferior cerebellar artery (PICA) is presented. Of the 130 reported cases of peripheral aneurysms of the PICA, 6 have been described as giant aneurysms and 5 have involved multiple aneurysms located on a single PICA. The occurrence of multiple aneurysms including one giant aneurysm has not been reported previously. A clinical description of our case as well as a review of the literature is presented.
