Bilateral extradural hematoma extending from the foramen magnum to the vertex

We present a 35-year-old man with an extradural hematoma extending bilaterally across the midline from the foramen magnum to the vertex who completely recovered following surgery. Because of the extent of the fluid collection, computed tomographic scanning proved invaluable in facilitating the planning of our surgical approach. He had a long history of alcohol abuse and there were features suggesting preexisting alcoholic brain atrophy in his postoperative computed tomography scan. The possible relationship of this finding to the size of the hematoma and the outcome is discussed.
