Abstract

BACKGROUND: Acute subdural hematoma (ASDH) is the most important cause of severe head injuries occurring during judo practice in Japan. Repeated head injuries have been reported as a cause of fatal ASDH, though the mechanism remains unknown. CASE DESCRIPTION: A 16-year-old male visited an emergency room with vomiting 3 days after a strong blow to the occipital region during judo practice. Although computed tomography (CT) was performed at that time, a small interhemispheric ASDH was overlooked. The patient sustained another head injury 19 days after the first, which led to convulsions and consciousness disturbance. The ASDH was increased in size on CT. We performed surgical evacuation, which revealed tearing of a bridging vein, after which the patient showed a good recovery.

CONCLUSIONS: It is important to be aware of the possibility of a small ASDH in concussed judo players following an initial impact, which may lead to subsequent fatal ASDH following another impact incident.
