Remote Cerebellar Hemorrhage After Surgery for an Unruptured Aneurysm

We report here on 2 cases of remote cerebellar hemorrhage (RCH) that developed after surgery for supratentorial unruptured aneurysm. In both cases, cerebral angiography was performed to diagnose the aneurysms and then screening was conducted for determining if there were any previous bleeding tendencies and comorbidities. After surgery, computed tomography (CT) was immediately performed to check for postoperative hemorrhage or infarction, and the images showed cerebellar hemorrhage that was relatively far away from the surgical site. We present the similarities of the 2 patients' preoperative angiography and CT and their perioperative blood pressure, and we discuss these findings to illuminate the pathophysiology of RCH.
