本篇報告一例鳥型分枝桿菌之肺部感染。病人為一位五十五歲女性，因咳血到門診求診，胸部影像學檢查發現病患有支氣管擴張症合併肺部小結節。痰液細菌培養初步發現為分枝桿菌，後來經鑑定為鳥型分枝桿菌感染。我們比較病患以前的胸部X光片發現肺部浸潤有更惡化的現象，於是開始使用藥物治療。鳥型分枝桿菌是非典型分枝桿菌在肺部感染中最常見的菌株。影像學上若表現為支氣管擴張症合併肺部小結節者，則應考慮病患是否感染非典型分枝桿菌，特別是鳥型分枝桿菌的感染。

Mycobacterium avium complex (MAC) is the most frequent pathogen causing nontuberculous mycobacterial pulmonary infection. Herein, we report a 55-year-old non-smoking female who had been diagnosed with bronchiectasis previously. She had also had small discrete nodules running a very slow, progressive course for at least 3 years, and was eventually diagnosed with MAC lung disease. In a patient with bronchiectatic imaging findings, especially with associated nodular lesions, pulmonary MAC infection may be considered as a possible etiology.
