M. Nagane et al., OSSIFIED AND CALCIFIED EPIDURAL HEMATOMA INCIDENTALLY FOUND 40 YEARS AFTER HEAD-INJURY - CASE-REPORT, Surgical neurology, 42(1), 1994, pp. 65-69
The authors report a 57-year-old man with an ossified and calcified ep
idural hematoma found incidentally 40 years after incurring a severe h
ead injury. Since the introduction of computed tomography (CT) scan, f
ew such cases have been described in the literature. A characteristic
intracranial ''double-outlined'' contour on plain skull x-ray films an
d CT scans represented bone formation and calcification of the hematom
a capsule adjacent to the dura.
