Core Tip

Core Tip: The differential diagnosis and management of biliary cystic neoplasms of the liver may be very challenging, especially in the setting of pregnancy. To the best of our knowledge, we describe herein the first case of a mucinous cystic neoplasm of the liver (MCN-L) with spontaneous rupture leading to the formation of a huge biloma in a pregnant woman. This was treated with percutaneous drainage of the biloma, followed by MCN-L removal via left hepatectomy with extrahepatic bile duct resection and anastomosis of the right hepatic duct with the Roux limb of the jejunum in the second trimester of pregnancy. We believe that the growth of this subepithelial stroma due to the high levels of sex hormones during pregnancy might have been the main causative factor that led to the tumour rupture and the formation of a biloma in our patient.
