Chronic Subdural Hematoma Presenting as Ataxic Hemiparesis

Abstract
A 57-year-old man was admitted for a typical left ataxic hemiparesis syndrome. He presented no vascular risk factor, with normal blood pressure. CT scan showed a frontoparietal right subdural hematoma. After surgery, the symptomatology disappeared completely. This observation reveals that subdural hematoma must be considered as a possible etiology of ataxic hemiparesis syndrome. The physiopathology is discussed.
