Cystadenoma originating from the gallbladder

Abstract

Biliary cystadenomas are very uncommon benign tumors. They are very rare occurrences in the gallbladder, and there are only a few case reports in the literature.(1-3) Cystadenomas are more frequently seen among middle-aged women. The clinical presentation varies and depends on the size and location of the cyst. They are unilocular or multilocular cystic tumors that contain septations. Although biliary cystadenomas are of a benign nature, they may recur after excision, nd there is a risk of development of cystadenosarcomas.(4-6) Hepatobiliary cystadenomas are most commonly seen in the liver (83%) followed by the extrahepatic biliary system (13%) and gallbladder (0.02%).(7)

In this report, we present the sonographic results of a rare case of cystadenoma originating in the gallbladder.
