Reversible Parkinsonism due to Chronic Subdural Hematoma: A Case Report

Abstract

Although Chronic Subdural Hematoma (CSDH) is frequent in elderly patients, the CSDH can exceptionally cause a parkinsonism or aggravation of pre-existing parkinsonism. Only 27 cases reversible parkinsonism due to chronic subdural hematoma was reported in the literature. Disappearance of the extra pyramidal symptoms followed craniotomy and removal of the CSDH suggest a cause-and-effect relation between the haematoma and the clinical symptomatology. A case of a 62-year-old man with a two weeks history of parkinsonism caused by a CSDH reversible after surgery evacuation of the haematoma is reported. CSDH is a rare cause of reversible parkinsonism after surgery. CT scan must be recognized in any acute Parkinsonism or any deterioration of preexisting Parkinson disease to diagnose the Parkinsonism secondary to CSDH.
