title: Isolated paratracheal mass of tuberculous origin in an adult patient.
abstract: A 40-year-old man presented with a solitary mediastinal (right paratracheal) mass which proved to be due to Mycobacterium tuberculosis. While the incidence of tuberculosis has diminished in our countries, such unusual manifestations of tuberculosis as the present case, are still encountered. Tuberculosis, the "perfect imitator", should be included in the differential diagnosis of a mediastinal mass. Excision for therapeutic, as well as histological and bacteriological diagnostic, purposes should be supplemented by appropriate antituberculous chemotherapy.
