Case Study: Gerstmann's syndrome associated with chronic subdural haematoma: a case report

Abstract

We report a patient who exhibited Gerstmann s syndrome in association with a chronic subdural haematoma. A 71 year old right handed woman presented with mild right arm and leg weakness that began 2 weeks prior to admission. Neurological examination on admission revealed a mild right hemiparesis. Neuropsychological examination revealed right-left disorientation, finger agnosia, agraphia, and acalculia, but no language disturbance. A computerized tomographic CT scan revealed a large left frontoparietal, extra axial hypodense fluid collection containing scattered hypodense foci. A left parietal evacuation of the haematoma was performed. Following surgery the patient dramatically improved. We suggest that the direct compression by the chronic subdural haematoma or a hemispheric pressure difference caused Gerstmann s syndrome. This is an unusual report of a Gerstmanns syndrome following chronic subdural haematoma.
