An unusual case of Pneumocystis carinii presenting as an aural mass

Extrapulmonary involvement of organs with the protozoan Pneumocystis carini i is rare. We describe a case of Pneumocystis carinii presenting as an eros ive aural mass in a young male patient with acquired immunodeficiency syndr ome. As far as the authors are aware such an example has never been describ ed in a British journal and is the first case worldwide where otic pneumocy stosis has extended into the middle cranial fossa. We also present a review of the literature on otological manifestations of Pneumocystis carinii.
