Abstract
A case of double origin of the posterior inferior cerebellar artery (PICA) is presented, with appearances on both cross-sectional imaging and conventional angiography. An associated aneurysm was found, strengthening the belief that this variation is associated with intracranial aneurysms. Furthermore, this is the first report of a right-sided double-origin PICA in a female patient, which calls into question the previously proposed male and left-sided preponderance of this variation.
