An unidentified man is brought to the emergency department by ambulance after he was found wandering in the middle of the road. On presentation, he is oriented only to self and does not remember his age or how he came to be in the middle of the road.

His temperature is 98.7°F (37°C), blood pressure is 131/70 mmHg, pulse is 87/min, and respirations are 18/min. Physical exam reveals an elderly appearing gentleman in no acute distress.

Given persistent confusion, a CT scan is obtained with the results shown in Figure A. Lumbar puncture shows a normal opening pressure with clear fluid.
