The authors report a 57-year-old man with an ossified and calcified epidural hematoma found incidentally 40 years after incurring a severe head injury. Since the introduction of computed tomography (CT) scan, few such cases have been described in the literature. A characteristic intracranial "double-outlined" contour on plain skull x-ray films and CT scans represented bone formation and calcification of the hematoma capsule adjacent to the dura.
