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 improve the patient's neurological condition. Clinical-pathological analysis confirmed the diagnosis of corticobasal degeneration (CBD) as an underlying disease relating to parkinsonism and aphasia. In patients with parkinsonism with high risks of falling, attention should be paid to neurological deterioration due to traumatic SAH-related hydrocephalus. Particularly, in patients with aphasia such as in those with CBD, delayed detection of posttraumatic complications might cause poor responsiveness to surgical intervention.
