Biliary Cystadenoma Causing Esophageal Varices

Biliary cystadenomas are benign but potentially malignant cystic neoplasm. They are rare multilocular cystic tumors of the liver that usually located in the right hepatic lobe. The incidence is less than 5% of intrahepatic cyst. Biliary cystadenomas present predominantly in middle-aged women. Radiological imaging, often abdomen computed tomography (CT), is fundamental in diagnosis. On CT image, biliary cystadenoma appears as a low attenuated mass, which may be unior multilocular, or may have septations. The preferred treatment is radical resection because it is difficult to differentiate a benign from a malignant biliary cystadenoma. Some patients present abdominal pain, nausea, vomiting, and obstructive jaundice. But, often they are asymptomatic. In some case biliary cystadenoma incidentally found during physical health examination. However, it is difficult to detect cystic tumor unless symptoms are presented. The lesions were incidentally found on abdominal images such as abdomen ultrasonography (US) or abdomen CT. But it is rare to associate esophageal varix with biliarycystadenoma.
