Chronic expanding epidural haematoma. Case report.
An encapsulated fluid epidural haematoma in a 9-year-old boy was successfully evacuated by a simple burr hole procedure 5 months after a minor head injury. Clinicopathological findings suggested that chronic expansion of an initially unsuspected epidural haematoma occurred as a result of repeated haemorrhages from the haematoma membrane, resulting in an unusually long delayed appearance of clinical evidence. This case demonstrates that a chronic expanding process similar to that seen in chronic subdural haematoma needs to be considered as a possible complication of epidural haematoma and indicates an important role for the haematoma membrane in the chronic expansion of epidural haematoma.
