A Case of Intramural Esophageal Bronchogenic Cyst.

A bronchogenic cyst is a congenital malformation with a rare esophageal origin. Occasionally, it is discovered incidentally, and excision is the only treatment. A 43-year-old patient was referred to our hospital for treatment of a cystic tumor in the left posterior mediastinum. We suspected the tumor was a bronchogenic cyst by imaging findings; therefore, we performed video-assisted thoracoscopic resection. The patient was discharged 9 days postoperatively. The tumor origin was found to be the esophageal wall. This report presents a rare case in which the esophageal wall was the origin of the bronchogenic cyst.
