title: Lower lobe pulmonary tuberculosis in immunocompetent male.
abstract: We present a case of 23-year-old student misdiagnosed for two months. Radiological finding showed a pneumonial infiltrate of left lung lower lobe. Antibiotical therapy was not resulting in a radiological regression. Biopsy of the lung infiltrate by transthoracic computed tomography guided histology needle, showed granulomatous inflammation with necrosis. Bronchial aspirate received by bronchoscopy was positive in culture on Mycobacterium tuberculosis. After 6 months of antituberculotic therapy advance the complete regression of lung infiltrate. Tuberculosis of lower lung lobe is difficult to diagnose, particularly in persons who are not immunocompromised or without associated diseases. Lower lobe localization of tuberculosis is between 0.6 to 10.5% in all cases. Early diagnosis and therapy of pulmonary tuberculosis depends on bronchoscopic samples. The biopsy of the lung infiltrate by transthoracic computed tomography guided histology needle in histopathological and bacteriological diagnosis of tuberculosis was also useful.
