Biliary mucinous cystic neoplasm with invasive carcinoma and recurrent cholangitis due to hepatolithiasis


Abstract

Biliary mucinous cystic neoplasms are very rare tumors. They are thought to be occurred due to malignant transformation of biliary cystadenoma. Biliary mucinous cystic neoplasm is commonly seen in women and more prevalent in fifth decade of life. Preoperative differential diagnosis of hepatic atypical cystic lesion is difficult. Biliary cystadenocarcinomas are usually multiloculated cystic lesions. Typical imaging characteristics are the existence of thick wall, thick and irregular internal septations, intramural nodules, papillary projections and contrast enhancement. However, they can appear with nonspecific imaging findings. Biliary cystadenoma and cystadenocarcinoma can mimic the imaging features of other cystic liver lesions. Therefore, the imaging findings of this rare case with the biliary mucinous cystadenocarcinoma associated with recurrent cholangitis and hepatolithiasis were presented.
