A pediatric chronic subdural hematoma after dodgeball head injury.

Chronic subdural hematoma is a subdural hematoma that is older than 3 weeks. Chronic subdural hematoma is predominantly a disease of the elderly and is rare in children. Its common manifestations are altered mental state and focal neurological deficits. We report here a rare case of chronic subdural hematoma in a 9-year-old child due to repeated minor dodgeball head injuries. Although such a case has never been reported in sport, the risk still exists. No altered mental state or focal neurological deficits were observed; the child presented with intermittent severe headache with nausea and vomiting. There was also no evidence of child abuse; however, the history of repeated minor head injuries during playing was significant.
