OBJECTIVE AND IMPORTANCE: This report presents a case in which cerebellar hemorrhage occurred after lumbar decompression surgery that was complicated by dural tear and prolonged cerebrospinal fluid leakage. Remote cerebellar hemorrhage after spinal surgery is extremely rare. Our objective is to describe this unusual complication, discuss the possible mechanisms of remote cerebellar hemorrhage, and review the literature. CLINICAL PRESENTATION: A 73-year-old woman underwent surgery for lumbar spinal stenosis. A dural tear occurred during decompression, and the patient developed remote cerebellar hemorrhage on postoperative Day 2. INTERVENTION: The cerebellar hemorrhage was treated surgically, and a biopsy of hemorrhagic brain parenchyma revealed an arteriovenous malformation. CONCLUSION: Although it is an extremely rare complication, remote cerebellar hemorrhage should be kept in mind as a possible complication of spinal surgery, especially in operations complicated by dural tears.
