Abstract

The author present a rare case of rapid ossification of epidural hematoma (EDH) in a 5-year-old boy. At admission, the computed tomography (CT) revealed an EDH on left temporoparietal region. On the follow-up CT scan doing 14 days after traffic accident, the expansion of the former hematoma was not visible, but the hematoma accompanied by the thin hyperdense layer on the dura. On follow-up CT scans, the hematoma was decreased but the ossified layer progressing. After 6 months of conservative therapy, the hematoma was fully absorbed and the ossified lesion merged to inner table of the skull. Hence, rapid ossification of an EDH should be considered in children and serial follow-up CT scans must be conducted.

  FIGURE 1 The progressive changes of epidural hematoma (EDH) and calcification on computed tomography (CT) scan. The brain CT on admission reveals left parietal EDH (A). A follow-up CT scan on 1 week later reveals the EDH that is slightly increased in volume (B). Two weeks later, CT scan shows that the EDH size is slightly decreased but a thick layer of calcification is revealed on the dural layer (C). The epidural calcification is growing in thickness of first 2-3 months (D, E). Six month after trauma, follow-up CT shows that the EDH has been fully absorbed, and the calcified lesion merged to inner table of skull (F).
