The most common neurologic manifestations of polycythemia vera (PV) are cerebral infarction and transient ischemic attacks, while cerebral hemorrhage or intracranial dissection has been rarely associated with PV. Here we report the first case of a 59-year-old patient with intracranial supraclinoid internal carotid artery (ICA) dissection causing cerebral infarction and concomitant subarachnoid hemorrhage due to pseudoaneurysm rupture as clinical onset of PV. This case report discusses the possible mechanism and treatment of this extremely rare condition.
