RADIOLOGY: HEPATOBILIARY: Case# 33117: CYSTIC HEPATIC MASS. 61-year-old woman with three year history of fatigue and enlarging right upper quadrant mass. 1. Large, non-enhancing, cystic hepatic mass. There is associated compression of the portal vein and inferior vena cava with resultant abnormal hepatic perfusion. Diagnostic considerations here would included a biliary neoplasm such as a biliary cystadenoma or cystadenocarcinoma, or perhaps a chronic abscess. If the patient has any history of foreign travel, a hydatid cyst would have to be included in the differential. 2. Perivaginal varicosities.
