FIG 2. Unenhanced CT scans of a 36-year-old male assault victim (initial CT scan 2 hours after injury).

A and B (at a level 5 mm contiguously higher than A), Scans show a left temporal EDH, 2 cm in width. The patient was neurologically normal at the time of the initial CT scan.

C and D (at a level 5 mm contiguously higher than C), Follow-up scans 10 hours later, after decline in neurologic status prompted repeat scanning. The EDH enlarged to 3 cm in width, associated with early ipsilateral uncal herniation. The patient underwent surgical evacuation and was discharged to a skilled nursing facility after a 17-day hospitalization.
