AbstractRemote cerebellar hemorrhage (RCH) following spinal surgery is extremely rare. We present two cases of RCH following cervical spinal surgery. The first case is a 71-year-old female. She underwent surgery for atlantoaxial subluxation and a subcutaneous suction drain was placed. Three hours after surgery, she became comatose and computed tomography (CT) revealed RCH. The second case is a 51-year-old female. She underwent surgery for ossification of posterior longitudinal ligament in the cervical spine. Intraoperatively, the dura was opened unintentionally and a subcutaneous suction drain was placed. She complained of a severe headache and nausea postoperatively, and CT obtained two days after the surgery demonstrated RCH. In both cases, drains contained much fluid, which was assumed to be consistent with cerebrospinal fluid. Both cases were managed conservatively and displayed no cerebellar symptoms on discharge. Rapid loss of a great amount of cerebrospinal fluid might be the causative factor of RCH. RCH might occur after any type of spinal surgery with dural tear or intradural manipulation. Early diagnosis is particularly important for the treatment of RCH following spinal surgery and spinal drainage might be useful to manage cerebrospinal fluid leakage.
