Cerebellar haemorrhage after repeated burr hole evacuation for chronic subdural haematoma.

We report a 79-year-old man whose third burr hole craniotomy evacuation for recurrent chronic subdural haematoma (CSDH) was complicated by cerebellar haemorrhage. The patient died 9 days later. Two previously documented cases in which this complication arose after evacuation of extra-axial collections also resulted in death. Remote cerebellar haemorrhage is a rare complication of neurosurgery but is associated with high mortality. This complication should be considered among the differential diagnoses after neurological deterioration following CSDH evacuation.
