We report an unusual case of extralobar pulmonary sequestration (ELS) with an associated cyst of mixed bronchogenic and esophageal type. A 58-year-old woman was incidentally found to have a 6 x 6 x 5 cm sized mass in the right superior mediastinum. The mass consisted of sequestrated pulmonary tissue and an unilocular cyst with a direct communication. The cyst could not be easily classified because it was lined by squamous or respiratory epithelium with two distinct muscle layers and bronchial glands. Bronchial cartilage was present in close proximity to the ELS. This unusual combination of ELS with a foregut cyst might be a part of bronchopulmonary foregut malformation, attributed to a common embryologic pathogenesis.
我们报告了一例罕见的叶外型肺隔离症（ELS），伴有一个混合性支气管源性和食管源性囊肿。一名58岁女性偶然发现右上纵隔有一个6×6×5cm大小的肿块。该肿块由隔离的肺组织和一个与之直接相通的单房囊肿组成。由于囊肿内衬鳞状或呼吸上皮，有两层不同的肌层和支气管腺体，因此难以轻易分类。支气管软骨紧邻ELS。这种ELS与前肠囊肿的不寻常组合可能是支气管肺前肠畸形的一部分，归因于共同的胚胎发病机制。
