[Calcified epidural hematoma-report of a case incidentally found 16 years after head injury (author's transl)].

A calcified epidural hydroma, or old hematoma, was incidentally found in the left parietal region of a 55-year-old man presenting status epilepticus due to uremia after a lapse of 16 years following head injury. The hydroma (10x7x1.2 cm) was extirpated operatirelly. There was an extensive calcificantion in the wall, and the outer wall showed bone-like metaplasia and hemosiderin deposit. No skull fracture was discernible. The dura and the brain surface neighboring the hydroma were gloslsly normal. The patient eventually died of uremia.
