Delayed Detection of Hydrocephalus following Mildly Traumatic Subarachnoid Hemorrhage in Corticobasal Degeneration: A Case Report

Abstract A 65-year-old woman presented with slowly progressive aphasia with gait disturbance associated with parkinsonism. She experienced a fall that resulted in a brain trauma. Brain imaging revealed a small amount of subarachnoid hemorrhage (SAH) with intraventricular bleeding. Despite conservative therapy, gait disturbance and hyporesponsiveness gradually deteriorated following that brain trauma. One month later, she was transferred to our hospital, and magnetic resonance imaging revealed prominent communicating hydrocephalus. A ventriculoperitoneal shunt and brain biopsy were performed. Neurosurgical intervention did not
