Pulmonary sequestration associated by Mycobacterium intracellulare infection

Abstract

A case of a 29-year-old woman with intralobar pulmonary sequestration infected with Mycobacterium intracellulare is presented. A chest CT scan revealed a density in the posterior segment of the left lower lobe, and an acid-fast bacillus sputum culture yielded Mycobacterium intracellulare. After 3 months of treatment with clarithromycin, streptomycin, rifampicin and ethambutol, the patient underwent partial resection of the left lower lobe. At the 6-month follow-up the patient's clinical status is excellent. A review of the literature revealed only three case reports of pulmonary sequestration associated with Mycobacterium aviumintracellulare complex infection.
