Nabil Ghaleb

The Mycobacterium terrae complex, consisting of three saprophytic species, (M. terrae, M. nonchromogenicum, and M. triviale), they rarely cause diseases in immunocompetent people. There are few case reports of lung involvement by Mycobacterium terrae complex. We reported a 13 years old immunompetent girl with a cavitary opacity seen on chest imaging and bronchoscopy revealed an endobronchial lesion, sputum and tissue specimens revealed growth of Mycobacterium triviale. Our patient is unique as it is the first case reported in Saudi Arabia with this type of Mycobacteria, in addition there is no case reported in the literature with Mycobacterium triviale with endobronchial lesion, the patient treated with a combination of rifampicin, ciprofloxacin and ethambutol for six months, she showed good response with resolution of radiological abnormalities and she did not have relapse after one year of follow up.
