Homogeneous well-defined cystic lesion measuring 14.5 x 14.5 cm, arising from the pancreatic tail displacing the adjacent structures. Thin enhancing wall, multiple thin septae and a few tiny peripheral calcifications are seen in it. No solid component is seen. Bulky postpartum uterus.
Impression: Large homogeneous well-defined pancreatic tail cystic lesion, which is likely a mucinous cystadenoma; other possible differential can be a pancreatic pseudocyst if there is any history of pancreatitis.
