Mycobacterium Shinjukuense Pulmonary Disease Progressed to Pleuritis after Iatrogenic Pneumothorax: A Case Report

Abstract

Mycobacterium shinjukuense is a newly identified nontuberculous mycobacteria (NTM) and its gene sequence of 16S rRNA shows high homology to that of Mycobacterium tuberculosis. We present a case of M. shinjukuense pulmonary disease progressed to pleuritis after iatrogenic pneumothorax. The patient was initially diagnosed as tuberculosis based on a positive result for the 16S rRNA of an M. tuberculosis identification kit using scrapings from the cavitary nodule. We need to bear in mind that pneumothorax following bronchoscopy may induce NTM pleuritis and M. shinjukuense infection should be considered in the differential diagnosis of mycobacterial pulmonary disease with effusion.
