Successful Surgical Management of Giant Mucinous Cystic Neoplasm of Liver (MCN-L) Presenting With Peritoneal Rupture and Biliary Prolapse: Case Report and Review of Literature

Mucinous cystic neoplasms of liver (MCN-L) are generally considered benign indolent cystic liver lesions, not associated with significant clinical symptoms in majority of patients. However, rarely these benign-appearing lesions may have a complicated clinical course, presenting with jaundice, acute abdomen, or malignant transformation. We report one such rare clinical presentation of MCN-L presenting with obstructive jaundice and abdominal pain due to prolapse of cystic component in biliary system and peritoneal rupture occurring simultaneously. Despite the complex nature of presentation, it was successfully managed surgically with normal follow-up imaging.
