Abstract:
A spontaneous dissecting Aneurysm of the posterior inferior cerebellar artery(PICA) is a very rare cause of subarachnoid hemorrhage(SAH) or ischemic stroke. We report a 53-year-old male patient with left PICA territory infarction due to the spontaneous dissection of the PICA. A Brain MRI revealed an infarction of the left PICA territory and an angiography showed spindle-shaped dilatations of the left PICA followed by an irregular luminal narrowing. An angiography taken 3 months later showed spontaneous resolution of the left PICA dissecting aneurysm. The management of the intracranial dissecting aneurysm is still controversial. Some authors recommend surgical approaches for the prevention of SAH while others present medical management. Our case showed spontaneous regression of the PICA dissecting aneurysm.
