[A case of bronchiectasis with abundant expectoration of Mycobacterium gordonae].
A 68 year old woman consulted our hospital because of 6 month history of dry cough. Her chest X-ray revealed bronchiectasis in the left lung. Three sputum specimens were culture positive for acid fast bacilli (AFB) 200 colonies. The bacilli were scotochromogenic, niacin test was negative and hydrolysis of tween 80 was positive, and they were identified as M. gordonae. M. gordonae is rarely implicated as a pathogen but a few reports suggest it may be pathogenic. Though our patient had clinical symptom and expected abundant M. gordonae, her chest X-ray revealed no progression. Thus, it was hardly possible to consider this case as a case caused by the infection with M. gordonae. In previous reports of M. gordonae pulmonary disease, chest X-ray findings showed cavity, infiltration and consolidation, however, no case with bronchiectasis was reported and chest X-ray findings of this case are interesting.
