Intrahepatic Biliary Cystadenoma Causing Luminal Common Bile Duct Obstruction

Abstract

Background: Biliary cystadenomas are rare cystic tumours that arise in the liver or less frequently in the extrahepatic biliary system. They are commoner in middle-aged women, their most favoured site is the right hepatic lobe. Methods: Case report and review of the literature. Results: We present only the second case of an intrahepatic cystadenoma causing luminal obstruction of the common bile duct. Clinical presentation is often non-specific and can prove to be a diagnostic challenge. Conclusion: Wide local excision of biliary cystadenomas is recommended, with regular radiological follow-up.

Differentiation Between Biliary Cystic Neoplasms and Simple Cysts of the Liver: Accuracy of CT

“…It is not a surprising result. This finding was also described in several previous studies as an imaging finding associated with biliary cystic neoplasms [11][12][13]; however, in those reports, the authors did not pay attention to the fact that this finding might be a significant feature for distinguishing between biliary cystic neoplasms and other common simple cysts [11][12][13]. Considering that biliary cystic neoplasms are mainly composed of sticky proteinaceous mucinous fluid, not the watery serous fluid that is the main component of simple hepatic cysts, it would be natural that biliary cystic neoplasms have a stronger mass effect on the surrounding tissues, such as the bile duct or vessels, than simple hepatic cysts [13].…”

Biliary Cystadenomas: A Case for Complete Resection

“…Acute presentation is often pain due to intracystic hemorrhage or rupture of the cyst and fever secondary to infection of the cyst [16]. Jaundice [17–19] is either due to an extrinsic compression of the bile duct [20], biliary obstruction by an intraluminal tumoural mass, or accretion of mucus secretion from a communicating biliary cystadenoma [20]. Ascites is secondary to compression of the inferior vena cava or the hepatic veins [19, 21, 22].…”

Biliary cystadenoma of the left intrahepatic duct (2007: 2b)

“…Biliary cystadenomas are rare hepatic neoplasms and can prove to be a diagnostic challenge due to their cystic aspect similar to other cystic liver lesions [1][2][3][4]; surgery is the treatment of choice [5]. In general, cystic liver lesions can be classified as developmental, neoplastic, inflammatory, or miscellaneous type [6].…”
