This 18 year old female came with a large left upper quadrant mass which had been growing for 1.5 years. Based on CT results, we thought we were dealing with a giant liver cyst. We were wrong. The patient had a giant retroperitoneal cyst of some type with the stomach, duodenum, pancreas and colon firmly attached to it. With careful dissection, we were able to dissect the cyst free.
