[Pleuro-pneumopathy revealing an unusual inhaled bronchial foreign body].

Inhalation of foreign bodies is not often observed in young adults, and may go unnoticed. A 37-year-old patient, with no significant medical history, was admitted for right basal pleuro-pneumopathy. Endoscopic examination revealed the presence of a brittle yellowish formation. It was a bone fragment, accidentally inhaled by the patient. It is necessary to look for an inhaled foreign body in cases of serious infection unusually observed in an immuno-competent patient.
