Abstract

Bronchogenic cysts are rare congenital malformations, most often occurring in the pulmonary parenchyma or posterior mediastinum. But they can develop in the ectopic area, especially in the retroperitoneal space. We report a case of adrenal bronchial cyst treated with laparoscopic excision. A 55-year-old woman was admitted with a left adrenal tumor on computed tomography during a study for dyspnea, cough, and sweats. The function of the adrenal glands was examined, and as a result, the adrenal tumors were determined to be nonfunctional. Magnetic resonance imaging showed about an 8-cm-sized large unilocular cystic lesion with mild and high signal intensities at left suprarenal fossa on T1 and T2 images. Iodine-123 metaiodobenzylguanidine scan showed no scintigraphic evidence of neuroendocrine tumor in the left adrenal gland. We performed laparoscopic adrenalectomy with transperitoneal approach. The round, cystic mass was completely excised saving normal adrenal tissues. The operative time was 75 minutes and there was no definitive bleeding and complication. The pathologic tissue weighed 35 g and measured 88 mm×45 mm×28 mm, and cystic changes were observed on the cut surface. The pathologic examination confirmed an adrenal bronchogenic cyst. We report a very rare disease, adrenal bronchial cyst, which could be easily and safely treated with laparoscopic surgery.
