First report of solitary cavitation nodules in the lungs with Mycobacterium canariasense.

INTRODUCTION

Mycobacterium canariasense is a relatively rare and rapidly growing nontuberculous mycobacterium (NTM) infection.

CASE REPORT

This case report describes a 36-year-old man with a Canariasense infection in the lung with solitary cavitation nodules located subpleural on CT scan, for which the final diagnosis was made by metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid (BALF-mNGS). It was successfully treated with levofloxacin and amikacin.

CONCLUSIONS

This experience is instructive because clinical diagnostic and CT imaging characteristics and treatment strategy guidelines for pulmonary infections caused by M. canariasense have not yet been established.
