Pulmonary Sequestration Associated by Mycobacterium intracellulare Infection.

Abstract

A case of a 29-year-old womanwith 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 Mycobacteriumaviumintracellulare complexinfection. (Internal Medicine 41: 990-992, 2002)

A Case of Congenital Cystic Adenomatoid Malformation Infected withMycobacterium avium-intracellulareComplex

“…A few case reports have detailed NTM infection in congenital lung lesions such as bronchogenic cysts8 and pulmonary sequestration9-11, and surgical resections were performed in all cases with or without anti-mycobacterial medication. However, NTM has never been described in the etiology of an infected CCAM.…”

Extralobar pulmonary sequestration infected with Mycobacterium gordonae

“…Few cases of intralobar pulmonary sequestration infected with tuberculous or nontuberculous Mycobacterium have been reported. [2][3][4] In those intralobar sequestration cases, Mycobacterium might have reached the sequestration through Kohn's pore or the bloodstream. A hematogenous route was less possible in our case because any other evident site of pulmonary or extrapulmonary Mycobacterial infection was absent.…”

“…1 Few cases of pulmonary sequestration infected with tuberculous or nontuberculous mycobacterium have been reported. [2][3][4] However, all of those reports were of intralobar pulmonary sequestrations. In the present article, we describe the first case of extralobar sequestration infected with Mycobacterium gordonae.…”

Atypical Mycobacterial Infection in Sequestrated Lung in an Infant Presenting with Chronic Pneumonitis and Recurrent Wheezing

“…Acute infections because of bacteria such as Staphylococcus and Pseudomonas 5 and chronic infections because of Aspergillus 6 and Nocardia 7 have been described. Infected pulmonary sequestration because of mycobacteria including M. tuberculosis , 8,9 M.kansasii , 10 and M. avium‐intracellulare 11 has been rarely reported. In our case, primary atypical mycobacterium was thought to be responsible for the granulomatous infection of the pulmonary sequestration in the absence of other pulmonary and extrapulmonary involvement.…”
