Traumatic porencephalic cyst and cholesteatoma of the ear

Porencephalic cyst expanding into the ear is a very rare complication of te mporal bone fracture. We report a case of a 20-year-old male who developed a traumatic porencephalic cyst of the temporal lobe expanding into the ear through a tegmen fracture in association with a cholesteatoma. The clinical presentation was otitic meningitis. This occurrence was not encountered in any of the cases reviewed in the lit erature. The diagnosis, pathogenesis, treatment and prognosis of this condi tion are reviewed.
