Acute epidural hematoma complicating Paget's disease of the skull.

Although among Anglo-Saxons Paget's disease is relatively common, it is very rare in Japan. The incidence of Paget's disease increases as age advances, and in elderly people over 90 years of age it can be seen in as many as 10%. On the other hand, acute epidural hematoma seldom occurs in the older generation, because dural adhesion to the internal table of the skull becomes more intense. We have encountered an 86-year old woman with advanced Paget's disease who developed an acute epidural hematoma after trivial head trauma. Acute epidural hematoma complicating Paget's disease has been reported only twice before and this case is the first report in Japan. The literature on the pathogenesis of the acute epidural hematoma complicating Paget's disease is reviewed.
