Benign cystic neoplasms of liver comprises of 5-10% of hepatic lesions. While simple cysts are common, biliary mucinous cystic tumors (BMCT) are rare tumors. We report various presentations of benign mucinous cystadenoma (BMCA), ranging from a small well defined cystic lesion to large lesions replacing one lobe of liver or involving multiple sectors of the liver, requiring a wide  range of surgical procedures to treat such tumors. Histopathology confirmed the diagnosis of benign biliary cystic neoplasm in all the cases. Rare occurrence, potentially malignant nature of the disease and difficulty in differentiating from other cystic hepatic lesions need careful evaluation of such cases to select the optimum management option. Keywords: Intrahepatic biliary mucinous cystic neoplasm, biliary mucinous cystadenocarcinoma, cystic hepatic tumor, biliary cystadenoma.
