Remote cerebellar hemorrhage is a usual complication after supratentorial craniotomy. Especially, only several cases have been reported regarding the occurrence of remote cerebellar hemorrhage after burr hole drainage for the treatment of chronic subdural hematoma (CSDH). In this paper, we present an elder patient with this rare postoperative complication. A 73-year-old man presented with dysarthria and right hemiparesis. Computed tomography (CT) demonstrated a left chronic subdural hematoma. Hematoma drainage through a single burr hole was perfomed. About 3 hours after the surgery, the patient became restless and presented nausea and dizziness with a relatively large amount of drainage of hematoma. CT revealed resolution of the subdural hematoma and bilateral cerebellar hemorrhage appearing as "zebra sign". Magnetic resonance angiography and 3D-CT angiography showed the normal structure of posterior circulation in both the arterial and venous phases. The remote cerebellar hemorrhage was suspected to have happened as a result of overdrainage of hematoma. Finally, he was discharged without any neurological deficits. Although remote cerebellar hemorrhage after drainage through a burr hole for the treatment of chronic subdural hematoma is a rare complication, it is necessary to be aware of the possibility of such a complication after supratentorial surgery.
