A Case of Bronchial Tuberculosis and Tuberculous Hilar Lymphadenitis Accompanying the Appearance of Intrapulmonary Shadows during the Initial Stage of Antituberculous Chemotherapy

A 24-year-old man complaining of fever was admitted to our hospital. He was diagnosed as having bronchial tuberculosis and tuberculous hilar and mediastinal lymphadenitis from chest X-ray, computed tomography and bronchofiberscopic findings. After 2 months of antituberculous therapy, patchy shadows appeared in the left middle lung field and expansion of the left lingular bronchial lesion was noted. Continuous use of the same drugs led to resolution of the lung shadows and the bronchial lesion. So we concluded that they were reversible roentgenographic progressions frequently observed at the initial stage of antituberculosis treatment. It was interesting that the apperance of the intrapulmonary shadow in this case might be associated with bronchial obstruction.
