Traumatic intracerebellar haematoma.

A case of traumatic intracerebellar hematoma is presented. The salient feature of the patient's early clinical course was delayed, rapid deterioration in the absence of antecedent focal neurological findings. The rarity of this lesion and its high mortality due to delay in correct diagnosis have been previously emphasized. Reported cases have followed a subacute clinical course and deterioration has been preceded by focal neurological findings. Prompt ventricular drainage followed by evacuation of the hematoma can be expected to yield a satisfactory clinical result.
