• Tuberculosis (TB) is a common worldwide airborne infection and it is a medical and social problem with high mortality and morbidity, especially in developing countries like Peru and Haiti that share the highest incidence of MDR and XDR TB.  • Pulmonary TB images depend on diverse aspects, being CT a highly sensitive technique in the detection of minimal exudative lesions, subtle or occult parenchymal disease and in assessing disease activity and treatment effectiveness. • Micronodules, nodules, “tree-in-bud” appearance, consolidation, and cavities are the most common CT findings in active pulmonary TB, whereas disappearance of tree-in-bud, pleural effusion and presence of fibrotic change appear to be indicators of treatment effectiveness. • Imaging appearances of MDR TB are the same as those of non-MDR TB, however, multiple cavities, nodules and bronchial dilatation seen on CT in young patients with acid-fast bacilli positive sputum, can suggest the presence of MDR TB or XDR TB rather than DS TB.
