FIG 3. Unenhanced CT scans of an 87-year-old woman struck by a car (initial CT scan 2 hours after injury).

A and B (at a level 15 mm higher than A), Scans show a 12-mm-wide high-right-convexity EDH with subarachnoid hemorrhage in the right parietal lobe inferiorly. The patient had a neurologic deficit, but surgery was not performed because of the patient's religious preferences. A further decline in neurologic status prompted a follow-up scan 9 hours later.

C and D (at a level 10 mm higher than C), Scans show an increase in width of the high-right-convexity EDH to 18 mm, with ipsilateral parenchymal hemorrhage and severe right to left midline shift. The patient did not survive the injury.
