Remote cerebellar hemorrhage after lumbar spinal fluid drainage. Report of two cases and literature review

Remote cerebellar hematoma, a cerebellar hematoma occurring after performing a surgical procedure in an anatomical distant area from the cerebellum, is a rare complication. It has been reported after supratentorial surgery and, less often, after spinal surgery with dural opening with important loss of cerebrospinal fluid. We report the occurrence of remote cerebellar hemorrhage after lumbar spinal fluid drainage in two patients with suspected normal pressure hydrocephalus. They were managed conservatively with good outcome. We review the pathologic mechanism, diagnostic procedures, management and prognosis of remote cerebellar hemorrhage.
