[A Case of Retroperitoneal Bronchogenic Cyst]

Abstract

A 75-year-old male visited a clinic with the chief complaint of pollakiuria. A computed tomography scan revealed, a left adrenal mass, and the patient was then referred to our hospital. Since a malignant tumor could not be ruled out. We performed laparoscopic left adrenal resection. Postoperative histopathological findings revealed the mass to be a bronchogenic cyst, which had no continuity with the normal adrenal gland. The postoperative course was uneventful, and recurrence has not been observed. Retroperitoneal bronchogenic cysts are rare and often difficult to diagnose preoperatively using imaging studies.
