title: Pulmonary infection caused byMycobacterium kansasii: findings on computed tomography of the chest.
abstract: OBJECTIVE
  To describe the main tomography findings in patients diagnosed with pulmonary infection caused byMycobacterium kansasii.
  
  
  METHODS
  Retrospective study of computed tomography scans of 19 patients with pulmonary infection byM. kansasii.
  
  
  RESULTS
  Of the 19 patients evaluated, 10 (52.6%) were male and 9 (47.4%) were female. The mean age of the patients was 58 years (range, 33-76 years). Computed tomography findings were as follows: architectural distortion, in 17 patients (89.5%); reticular opacities and bronchiectasis, in 16 (84.2%); cavities, in 14 (73.7%); centrilobular nodules, in 13 (68.4%); small consolidations, in 10 (52.6%); atelectasis and large consolidations, in 9 (47.4%); subpleural blebs and emphysema, in 6 (31.6%); and adenopathy, in 1 (5.3%).
  
  
  CONCLUSIONS
  There was a predominance of cavities, as well as of involvement of the small and large airways. The airway disease was characterized by bronchiectasis and bronchiolitis presenting as centrilobular nodules.
