Cerebellar haemorrhage after evacuation of an acute supratentorial subdural haematoma

Recent reports have highlighted the unusual complication of distant cerebel lar haemorrhage after supratentorial craniotomy, with only 25 previous case s reported in the literature. Nearly all reported cases occurred after cran iotomy for temporal lobectomy or for deep seated intracerebral pathology re quiring brain retraction and removal of CSF at surgery. Only one previous c ase of a cerebellar haemorrhage after evacuation of an extracerebral fluid collection has been reported. We describe the case of a cerebellar haemorrh age complicating the evacuation of an acute/subacute supratentorial subdura l haematoma in a 83-year-old woman. The literature is reviewed and possible mechanisms of haemorrhage discussed.
