Abstract

Mycobacterium fortuitum usually causes colonization or transient infection in patients with underlying lung disease, such as prior tuberculosis or bronchiectasis. The majority of these patients may not need to receive antibiotic therapy for M. fortuitum isolates. We report here on a patient with M. fortuitum lung disease and who was successfully treated with combination oral antibiotic therapy. A 53-year-old woman was referred to our institution because of purulent sputum and dyspnea. A chest radiograph and computed tomography scan revealed cavitary consolidation in the left upper lobe and multiple small cavities in the left lower lobe. Numerous acid-fast bacilli (AFB) were seen in multiple sputum specimens and M. fortuitum was identified by culture from the sputum specimens. The patient received antibiotic treatment including clarithromycin, ciprofloxacin and sulfamethoxazole, because her symptoms were worsening despite conservative treatment. Sputum conversion was achieved after one month of antibiotic therapy. Both the patient's symptoms and radiographic findings improved after 10 months of antibiotic therapy.

M. fortuitum은 호흡기 검체에서 동정되는 경우 대부분 집락화나 일시적인 감염으로 여겨지고 있고, 다른 NTM 폐질환처럼 장기간의 항생제 치료가 필요한 경우는 드물다. 저자들은 객담 항산균 도말과 배양검사에서 강양성을 보이면서, 임상증상과 방사선의 악화소견을 보여 장기간의 경구용 항생제 치료를 실시한 M. fortuitum 폐질환 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
