CT evolution of an acute venous epidural hematoma.

Acute traumatic epidural hematoma may develop secondary to an arterial or venous bleed. The computed tomography (CT scan) appearance of the hematoma depends on the source and severity of bleeding, the interval between injury and CT scan, and the degree of clot organization or breakdown. We report the emergency evaluation, CT scan evolution, and clinical management of one such acute venous epidural hematoma.
