摘要

肺隔離是罕見的先天或後天性下呼吸道畸形。在解剖分類上，有位於肺葉內肺隔離與擁有獨立臟層胸膜的肺葉外肺隔離。重複地細茵性肺部感染是肺隔離最常見之併發症。星形奴卡氏菌感染，一般被認為是免疫力低下病人的伺機性感染症。性荷爾蒙已被證實會影響細胞性免疫反應。我們在此報告一位因子宮內膜增生合併出血而長期服用女性荷爾蒙－黃體激素的中年婦女，雖以抗生素治療，仍有反覆「呼吸道感染，經手術治療，證實為肺葉外肺隔離合併星形奴卡氏茵感染。

Bronchopulmonary sequestration is a rare congenital or acquired malformation of the lower respiratory tract. Sequestrations are classified anatomically as intralobar sequestration, located within the normal lobe, and extralobar sequestration, located outside the normal lobe and with its own visceral pleura. Pulmonary infection, mainly bacterial, is the most common complication of bronchopulmonary sequestration. Nocardiosis is characteristically thought as an opportunistic infection in immuno-compromised patients. Sex hormones can influence cell-mediated immunity and predispose to such infection. We report the case of a middle aged woman with a concurrent history of symptomatic endometriosis under long-term treatment with medroxyprogesterone acetate, and in whom an extralobar sequestration complicated by Nocardia asteroides infection was diagnosed by video-assisted thoracoscopic surgery.
