A case of vertebral artery dissection coincides with ipsilateral posterior inferior cerebellar artery dissection

摘要

Sir,Dissection of the vertebral artery (VA) and posterior inferior cerebellar artery (PICA) is extremely rare even in cases of intracranial arterial dissection and most cases present with either subarachnoid hemorrhage (SAH) or cerebellar/brainstem infarction. We report our experience with VA dissection followed by spontaneous ipsilateral PICA dissection.
