Bronchogenic cysts originate from anomalous development of the ventral foregut. Although treatment of asymptomatic bronchogenic cysts remains controversial, symptomatic bronchogenic cysts should be surgically removed. We report a case of a 62-year-old man with an infected bronchogenic cyst. We drained the cyst using transesophageal endoscopic ultrasonography to control the inflammation and decrease the size of the cyst; we subsequently resected the cyst. Five months after resection, the patient was well, and computed tomography showed no evidence of cyst recurrence.
