title: Extralobar pulmonary sequestration in the middle mediastinum.
abstract: We here report a patients with an uncommon extralobar pulmonary sequestration located in the middle mediastinum in a 42-year-old female. Chest computed tomography showed a middle mediastinal mass of 6.5 × 2.7 × 2.0 cm in size, which consisted of some cystic lesions and a solid component. The mass was completely excised via a 3-port video-assisted thoracoscopic approach. Histopathologic examination revealed a cystic cartilaginous wall lined with ciliated columnar epithelium and edematous lung tissue, resulting in an extralobar pulmonary sequestration.
