[Fever, productive cough, night sweats].

A 43 year old male complained about fever, productive cough and nocturnal sweating. He was treated for pneumonia with antibiotics because of pulmonary infiltrate. Tomography revealed a large cavity with infiltrated border in the right inferior lobe. By means of bronchoscopy the diagnosis of bronchial tuberculosis was established. Mycobacterium tuberculosis was cultured. A comparison with previous radiographs suggested a duration of the disease of approximately 3 years. A combined chemotherapy with isoniazide, rifampicin and pyrazinamide resulted in rapid disappearance of symptoms and to regression of radiologic changes. The cavity persisted after 9 month of treatment.
