Acute tentorial subdural hematoma as a false-positive in indium-111 leukocyte scintigraphy.
A case of acute tentorial subdural hematoma detected by In-111 leukocyte scintigraphy and confirmed by CT brain scan is herein described. White blood cells are an integral part of the blood pool and labeled white cells freely leave the intravascular space in case of active bleeding. Acute hemorrhage and hematoma can thus be a cause of a false-positive study.
