Pulmonary Tuberculosis After Lung Transplantation

During a 5-year study period, we diagnosed pulmonary tuberculosis in two (2%) of 94 lung and heart-lung transplant recipients. Each infection occurred 3 months after bilateral lung transplantation in the presence of evidence implicating donor-to-recipient transmission of the pathogen. The radiographic patterns of pulmonary tuberculosis were subtle: narrowing of the middle lobe bronchus of the right lung caused by an endobronchial granulomatous mass (n = 1) and a focal cluster of small nodules in the upper lobe of the left lung and small bilateral pleural effusions (n = 1). Each patient achieved complete clinical and radiographic response after antituberculous therapy. We conclude that Mycobacterium tuberculosis may be transmitted directly by a donor lung and may involve bronchial mucosa, pulmonary parenchyma, and pleura.
