==Overview==
'''Biliary cystadenomas''' are uncommon unilocular or multilocular cystic neoplasms that may occur within the liver (infrequently found in the extrahepatic biliary tree and gallbladder).


Although biliary cystadenomas are benign tumors, they may recur after excision and have potential to develop into biliary cystadenocarcinoma.

==Pathophysiology==
{{SK}} Cystadenoma of biliary tract; Cystadenoma of biliary tree; Cystadenoma of biliary system; Biliary cystadenomas; Hepatobiliary cystadenoma; Intrahepatic bile duct cystadenoma; Cystadenocarcinoma of biliary tract; Cystadenocarcinoma of biliary tract; Intrahepatic bile duct cystadenocarcinoma; Hepatobiliary cystadenocarcinoma; Cystadenocarcinoma of biliary system
==Microscopic Pathology==
At histologic analysis, cystadenomas have multiple loculations lined by cuboidal or columnar epithelium that resembles biliary epithelium.

==Epidemiology and Demographics==
==[[Biliary cystadenoma and cystadenocarcinoma classification|Classification]]==


Cystadenomas occur predominantly in middle-aged women.
==[[Biliary cystadenoma and cystadenocarcinoma pathophysiology|Pathophysiology]]==


==Diagnosis==
==[[Biliary cystadenoma and cystadenocarcinoma causes|Causes]]==


The clinical presentation is variable, depending on the size and location of the cyst. Abdominal pain, obstructive jaundice, palpable mass, increasing abdominal girth, nausea, and vomiting are common signs and symptoms.
==[[Biliary cystadenoma and cystadenocarcinoma differential diagnosis|Differentiating Biliary cystadenoma and cystadenocarcinoma from other Diseases]]==


Biliary cystadenomas range in size from 3 to 40 cm. Large cystadenomas may demonstrate mass effect on adjacent organs or may be associated with [[hepatomegaly]].
==[[Biliary cystadenoma and cystadenocarcinoma epidemiology and demographics|Epidemiology and Demographics]]==


There are no specific imaging features that permit reliable differentiation of biliary cystadenoma from cystadenocarcinoma.
==[[Biliary cystadenoma and cystadenocarcinoma risk factors|Risk Factors]]==


===Computed Tomography===
==[[Biliary cystadenoma and cystadenocarcinoma screening|Screening]]==


*The CT attenuation of the fluid component in a biliary cystadenoma varies depending on the fluid content.
==[[Biliary cystadenoma and cystadenocarcinoma natural history, complications and prognosis|Natural History, Complications and Prognosis]]==
*Higher attenuation may indicate recent hemorrhage.
*Calcifications that may be present in the septa or cyst wall are typically more apparent with CT than other imaging modalities.
*Septa may enhance with contrast material.

==Treatment==
*The MR signal intensity of biliary cystadenoma is variable on both T1- and T2-weighted images, depending on the content of the cyst fluid.

*At US, a biliary cystadenoma appears as a unilocular or multilocular cyst with enhanced through transmission.
*Acoustic shadowing may be present from septal or wall calcification.
*The cyst fluid may contain low-level echoes from blood products, mucin, or proteinaceous fluid. Serous and bilious cyst fluid is generally anechoic.
*Echogenic mural nodules and papillary projections may be present.
