title: A retroperitoneal bronchogenic cyst mimicking a pancreatic or adrenal mass.
abstract: Retroperitoneal location of bronchogenic cysts is extremely rare. Most commonly they are encountered in the posterior mediastinum. Bronchogenic cysts arise from developmental aberrations of the tracheobronchial tree in the early embryologic period. We report a 42-year-old female patient with a retroperitoneal bronchogenic cyst in the left adrenal region. She was admitted to our hospital with epigastric pain and subsequently underwent CT of the abdomen. The examination revealed a mass related to the left adrenal gland. Endocrine tests for adrenal hypersecretion were negative. Because of the uncertain entity, laparoscopic adrenalectomy was performed. Pathological examination revealed a bronchogenic cyst in proximity to an inconspicuous left adrenal gland. Although very rare, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions and surgical resection pursued for symptom resolution and to establish a definitive histology.
