A large well-defined cyst containing turbid contents and multiple thin septations, measuring 13 x 15 cm, likely arising from the tail of the pancreas, is seen in the epigastric region. No solid component or significant internal vascularity is appreciable in it.

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.
Case Discussion
Procedure: Distal pancreatectomy and splenectomy.
Gross Description: The pancreatic cystic lesion measures 16 x 14 x 13 cm and weighs 161 grams.
Diagnosis: Mucinous cystadenoma of the pancreas, measuring 16 cm.
