Diagnostic scintigraphic sign in epidural hematoma at the vertex: case report.

Brain scintigraphy was described in a case of vertical (biparasagittal) epidural hematoma confirmed by contrast angiography. The anterior dynamic and static studies showed inferior displacement of the superior sagittal sinus, diagnostic of an epidural collection. Delayed static anterior and lateral images showed an increased vertical uptake with a crescentic and straight inner contour, respectively. A transaxial computed tomographic scan was negative.
