Biliary cystadenoma

Evaluation of biliary cystadenoma and cystadenocarcinoma

“…Biliary cystadenomas and cystadenocarcinomas are usually large multiloculated tumors, measuring from 3.5 to 25 cm in diameter, most frequently occurring in the right lobe of the liver [1][2][3][4][5]. They develop from the bile ducts; 85% intrahepatic and 15% extrahepatic.…”

“…ERCP to investigate the cause of jaundice may demonstrate communication of the tumors with the bile ducts. While percutaneous cyst aspiration can provide fluid for evaluation and permit contrast opacification of the tumor [5], the fluid obtained from biliary cystadenomas is usually nonspecific, and the internal morphology is well seen on ultrasound. Cyst aspiration may be helpful in excluding hepatic abscess or cystic hepatic metastasis.…”

Primary intrahepatic biliary cystadenomatous tumors

“…The differential diagnosis includes congenital hepatic cysts, hydatid cyst, hepatic abscess, cystic hamartoma, hepatoma, primary or metastatic necrotic neoplasms, metastatic cystadenocarcinomas, Caroli's disease, post- traumatic cyst, and polycystic disease [5,12,13]. In countries with a high prevalence of hydatid disease, the suspicion of a cystadenomatous tumor should always arise when negative serological tests are combined with a cyst that is septated whose content has a density higher than that of water on CT [14][15][16].…”

“…The treatment of choice is radical excision of the mass, either with a wide margin of normal liver or by means of a typical lobectomy, depending on the size and the location of the lesion [3,12,13]. Aspiration, sclerosis, marsupialization, and internal drainage must be avoided.…”

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

“…On the other hand, because biliary cystic neoplasms may be malignant, complete excision by surgery is the treatment of choice [5][6][7][8]. Therefore, accurate differentiation of biliary cystic neoplasms from simple cysts is crucial for the appropriate management of patients with large cystic lesions in the liver.…”
