An unexpected finding in a lucky elderly man.

A 95-year-old man with Alzheimer’s disease and diabetes mellitus was admitted because of a nonsyncopal fall resulting in a head injury while in the toilet. On physical examination, his Glasgow Coma Scale score was 14/15 (eye 4, verbal 4, motor 6) and no external injuries or focal neurological deficit was evident. Cardiovascular, respiratory, and abdominal examination findings were unremarkable. Plain computed tomography (CT) of the brain was performed (Fig 1). His blood glucose concentration was normal.
