Abstract

Bronchogenic cysts are primitive, foregut-derived developmental anomalies with bronchial-type, pseudostratified cylindrical epithelium. They are usually discovered in the thorax. The occurrence of such cysts in the retroperitoneum is extremely rare. Imaging techniques are generally effective in the detection of retroperitoneal bronchogenic cyst. Here, we report two cases (a 27-year-old man and a 33-year-old man) who had no clinical symptoms and were found by chance to have masses in the adrenal gland area during routine physical examination. We found that they had some similar computed tomography imaging features, including complete adrenal structure, cystic fusiform mass in adrenal region, and inclusion of calcifications in the lesions. However, accurate preoperative diagnosis remains difficult and only histology can provide a definitive diagnosis. Surgery remains the treatment of choice.
