Clinical symptoms of remote cerebellar hemorrhage are often mild and transient. One of our patients developed cerebellar hemorrhage in the left hemisphere after left fronto-orbito-zygomatic craniotomy. The other patient developed cerebellar hemorrhage in the vermis and bilateral hemispheres after T12–L2 laminectomy with the patient in the prone position, during which the dura mater was opened for tumor excision. Both of patients were treated conservatively and the second one had mild residual dysarthria and gait ataxia 6 months after surgery. Cerebellar hemorrhage must be considered in patients with unexplained neurological deterioration after spinal surgery and supratentorial craniotomy. The most important pathomechanism leading to remote cerebellar hemorrhage after spinal surgery and supratentorial craniotomy has been known to be venous bleeding due to caudal sagging of cerebellum by rapid leak of large amount of cerebro spinal fluid which seems to be related in our two cases. Minimizing cerebro spinal fluid loss during surgery would be helpful to prevent postoperative remote cerebellar hemorrhage.
