Parkinsonian syndrome associated with subacute subdural haematoma and its effective surgical treatment: a case report.

There have been several reports of parkinsonian syndrome arising from a mass effect from subdural haematomas. In this study, we present a case of parkinsonian syndrome caused by a subacute subdural haematoma. Evacuation of the haematoma resulted in the disappearance of parkinsonian symptoms in this case. Parkinsonism is not common complication of subdural haematoma; surgical treatment of those cases is associated with favourable outcome, without the need for antiparkinsonian medication.
