Serial CT findings of a rapidly calcified epidural hematoma in a young adult: a case report.

We report serial computed tomography (CT) findings in a rare case of a rapidly calcified epidural hematoma. A 21-year-old female patient was admitted to our hospital after being involved in a motor vehicle accident. An initial cranial CT revealed a right frontal bone fracture. She complained of right frontal headache, but showed no neurological deficit or tendency for bleeding. Therefore, she was treated conservatively without surgical intervention. Follow-up CT revealed an ossified epidural hematoma (EDH) 17 days after the head injury, and the ossification later thickened. However, a decrease in the width of the EDH was observed during the 9 months of follow-up during which serial CT images were acquired. The EDH resolved 9 months after the initial trauma, but the calcification layer remained thickened.
