Abstract

Abstract Objective: To describe the main tomography findings in patients diagnosed with pulmonary infection caused by Mycobacterium kansasii. Materials and Methods: Retrospective study of computed tomography scans of 19 patients with pulmonary infection by M. 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%). Conclusion: 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.Resumo Objetivo: Descrever os achados tomográficos de pacientes com diagnóstico de infecção pulmonar pelo Mycobacterium kansasii. Materiais e Métodos: Estudo retrospectivo dos exames de tomografia computadorizada do tórax de 19 pacientes com infecção pulmonar pelo M. kansasii. Resultados: Dos 19 pacientes avaliados, 10 (52,6%) eram do sexo masculino e 9 (47,4%) eram do sexo feminino. A média de idade do grupo foi 58 anos, com variação entre 33 e 76 anos. As alterações encontradas nos exames de tomografia computadorizada foram distorção arquitetural em 17 pacientes (89,5%), opacidades reticulares e bronquiectasias em 16 (84,2%), cavidades em 14 (73,7%), nódulos centrolobulares em 13 (68,4%), pequenas consolidações em 10 (52,6%), atelectasias e grandes consolidações em 9 (47,4%), bolhas subpleurais e enfisema em 6 (31,6%) e linfonodomegalias em 1 paciente (5,3%). Conclusão: Houve predomínio de cavidades e do padrão de acometimento de pequenas e grandes vias aéreas. A doença de vias aéreas foi caracterizada por bronquiectasias e bronquiolites que se manifestaram como nódulos centrolobulares.
