[Rapid disappearance of acute epidural hematoma by percutaneous aspiration of subperiosteal hematoma--case report].

We present the case of an 8-year-old boy who was injured in a bicycle accident and was admitted with a right frontal skull fracture, an acute epidural hematoma, a right frontal laceration, and a subperiosteal hematoma on admission. After the frontal cutaneous suture, the subperiosteal hematoma was aspirated by the percutaneous needle. Two hours later, a CT scan revealed that the epidural hematoma was disappeared. It is speculated that the subperiosteal and epidural hematoma communicated via the skull fracture thus necessitating the evacuation of the epidural hematoma by subperiosteal aspiration.
