A foregut cyst is formed as a result of abnormal budding and pinching of the tracheobronchial tree when bronchial buds develop to form the primitive respiratory tree. Foregut cysts are clinically classified as bronchogenic, esophageal, enterogastric, or ciliated hepatic. We present a foregut cyst that occurred in the retroperitoneum and was difficult to distinguish from other retroperitoneal cystic mass lesions. Magnetic resonance imaging was useful in revealing the cyst's continuity to adjacent organs.
