Abstract

Traumatic acute subdural hematoma (ASDH) patients are generally positive for fibrin/fibrinogen degradation product (FDP) or d-dimer. We herein report a patient with negative FDP findings who had ASDH on computed tomography (CT). A 71-year-old woman was hit by a light truck while riding on a motorcycle. She suffered recent memory disturbance. The FDP level after arrival at the hospital was negative; however, she had right, thin ASDH on CT. The post-admission course was uneventful. The takeaway from the present case is that physicians cannot deny the possibility of ASDH even when the FDP level in the acute phase is within the normal limits.
