A case of endobronchial tuberculosis with left main bronchial stenosis and atelectasis of left lower lobe in a 26-year-old female is reported. She had taken antituberclous agents for 9 months, but she complained of chest pain and coughing. Bronchoscopy revealed patency of left upper bronchus and bronchiectasis of left lower lobe. She underwent left lower lobectomy with bronchoplasty. After the operation she had significant improvement of pulmonary function. Although surgical treatment of endobronchial tuberculosis is controversial, bronchoplastic surgery can be an effective treatment of tuberculous bronchial stenosis because it relieves patients from symptoms by preserving lung functions.
