A 50-year-old woman of Caribbean descent presented to an outside hospital with a history of several months of recurrent postprandial right upper quadrant pain associated with nausea and vomiting. Her white blood cell count and liver function test results were within normal limits. She underwent abdominal ultrasonography and a computed tomography scan of the abdomen, which showed cholelithiasis and a questionable cystic dilatation of the common bile duct. She requested a transfer to the Weill Cornell Medical Center. Serologic test results for Echinococcus were negative. A magnetic resonance cholangiopancreatography was ordered to characterize the anatomy. This showed a roundlesion centered in the hepatic hilum measuring 1.9 × 1.9 × 2.1 cm with thin internal septations (Figure 1). Although it was in proximity to biliary structures, a direct communication was not visualized. There was no evidence of lymphadenopathy. She was scheduled for a laparoscopic cholecystectomy and resection of the lesion (Figure 2).

Figure 2. Laparoscopic and specimen images. A, Laparoscopic view at exploration. The gallbladder (a) is in close contact with the lesion (b), which is near the common hepatic duct (c) and the common bile duct (d). B, Macroscopic view of the lesion. Infundibulum of the gallbladder (a), proximal portion of the cystic duct (valves of Heister) (b), and cystadenoma (c).
A. Mirizzi syndrome
B. Carcinoma of the gallbladder
C. Cystadenoma of the cystic duct
