This MRCP image also shows the relation of the cyst to the gallbladder. The cystic mass is a choledochal cyst. This is an uncommon lesion that is often asymptomatic as in this case. Because patients with a choledochal cyst have a higher risk in developing a bile duct carcinoma, these lesions are usually surgically treated although they are asymptomatic. The lesion must be differentiated from other cysts in the upper abdomen such as the large liver cyst shown on the images below.
