Acute subdural hematoma with rapid resolution in infancy: case report

An infant who suffered acute subdural hematoma due to minor head trauma twice in a short period is presented. Each subdural hematoma, showing high density on computed tomographic scanning, resolved with unusual rapidity, resulting in full recovery after nonsurgical management. The mechanism of this rapid resolution of each hematoma was thought to be participation of cerebrospinal fluid secondary to a tearing of the arachnoid membrane.
