Low pressure traumatic epidural hematoma in a child with a prior hemispherectomy: Case report.

A 2½-year-old male child with a prior history of a left anatomic hemispherectomy to treat refractory epilepsy fell down two steps, striking his head on the ipsilateral side of the hemispherectomy. He presented with non-consolable crying and emesis. CT scan of the head demonstrated a left frontal epidural hematoma beneath the site of his prior craniectomy. The patient was initially treated by close observation. However, due to an increase in the hematoma from 29.5 to 49.3 ml over a 12-hour period along with the patient's lack of clinical improvement, surgical evacuation was performed. Intraoperatively, the source of the hemorrhage was found to be the skull fracture. Postoperatively, he returned to his neurologic baseline and was discharged home on postoperative day 3.
