Objetivo: As infecções respiratórias constituem a principal causa de morbidade e mortalidade em transplantados de órgãos sólidos. Lung transplantation Diagnostic imaging Mycobacterium infections Thoracic diseases Tomography, X-Ray computed/methods Tuberculosis, pulmonary. These findings are similar to those reported for immunocompetent patients with pulmonary tuberculosis and considerably different from those reported for AIDS patients with the same disease. Conclusions: The predominant HRCT pattern was ground-glass attenuation with consolidation, followed by cavitation and centrilobular nodules with a tree-in-bud pattern. Despite treatment, one-year mortality was 47.3%. Among the patients with cavitation and centrilobular nodules with a tree-in-bud pattern, the distribution was within the upper lobes in 66.6%. Among those 19 patients, the most common HRCT patterns were ground-glass attenuation with consolidation (in 42%) cavitation and centrilobular nodules with a tree-in-bud pattern (in 31.5%) and mediastinal lymph node enlargement (in 15.7%). Results: We evaluated 402 lung transplant recipients, 19 of whom developed pulmonary tuberculosis after transplantation. The HRCT findings were classified as miliary nodules cavitation and centrilobular nodules with a tree-in-bud pattern ground-glass attenuation with consolidation mediastinal lymph node enlargement or pleural effusion. Methods: From two hospitals in southern Brazil, we collected the following data on lung transplant recipients who developed pulmonary tuberculosis: gender age symptoms the lung disease that led to transplantation HRCT pattern distribution of findings time from transplantation to pulmonary tuberculosis and mortality rate. Therefore, we attempted to describe the HRCT patterns of pulmonary tuberculosis in lung transplant recipients. Greater understanding of those presentations could reduce the impact of the disease by facilitating early diagnosis. On imaging, tuberculosis has various presentations. The incidence of pulmonary tuberculosis is high among such patients. Objective: Respiratory infections constitute a major cause of morbidity and mortality in solid organ transplant recipients.
