Diagnostic Odyssey: Unveiling a Giant-infected Mucinous Cystadenoma of the Liver

Abstract Hepatic mucinous cystadenomas are rare cystic tumors that account for <5% of all liver cysts. These neoplasms can arise within the hepatic parenchyma or, less commonly, in the extrahepatic bile ducts. They are seen exclusively in females. They are usually symptomatic but occasionally may be detected incidentally. They may present with features of compression of adjacent organs or as dull aching pain. No cases have been reported of hepatic mucinous cystadenoma filled with purulent material. We present the rare case of a giant-infected mucinous cystadenoma of the liver in a young female, successfully managed with cystopericystectomy and segmentectomy.
