Department of Medical Ultrasound, Center of Minimally Invasive Treatment for Tumor, Shanghai Tenth People's Hospital; Ultrasound Research and Education Institute, Clinical Research Center for Interventional Medicine, School of Medicine, Tongji University, Shanghai, China.

Biliary cystadenocarcinoma (BCAC) is an extremely rare intrahepatic cystic tumor. Patients usually present with nonspecific symptoms such as abdominal pain, abdominal distention, and abdominal mass. This tumor occurs most commonly in the left hemiliver and is thought to mainly develop from a benign biliary cystadenoma (BCA). Read More

Differentiation of mucinous cysts and simple cysts of the liver using preoperative imaging.

Abdom Radiol (NY) 2022 04 21;47(4):1333-1340. Epub 2022 Feb 21.

Department of Radiology, Memorial Sloan Kettering Cancer Center, New York, NY, USA.

Purpose: Preoperative radiographic differentiation of mucinous cystic neoplasms (MCN) and simple cysts (SLC) of the liver is challenging. Previous data have demonstrated that the finding of septations arising from the cyst wall without indentation on cross-sectional imaging is associated with MCN. We aim to assess whether this radiographic feature is diagnostic of MCN. Read More

Pancreatic serous cystadenocarcinoma diagnosed with liver metastasis at 7 years after the resection of the primary serous neoplastic lesion.

Clin J Gastroenterol 2022 Apr 11;15(2):505-512. Epub 2022 Jan 11.

Department of Pathology, International University of Health and Welfare, Mita Hospital, 1-4-3 Mita, Minato-ku, Tokyo, 108-8329, Japan.

Pancreatic serous neoplasms are rare tumors that are usually benign. However, histopathological differentiation between benign (serous cystadenoma) and malignant (serous cystadenocarcinoma) lesions is difficult. We present the case of a patient with pancreatic serous cystadenocarcinoma that was diagnosed with liver metastasis 7 years after the resection of the primary serous neoplastic lesion. Read More

Hepatobiliary mucinous cystic neoplasms and mimics.

Abdom Radiol (NY) 2021 Oct 23. Epub 2021 Oct 23.

Mallinckrodt Institute of Radiology, St. Louis, MO, 63110, USA.

This review will provide an overview of hepatobiliary mucinous cystic neoplasms and their mimics such as complex appearing benign cysts, intraductal papillary neoplasm of bile ducts, choledochal cysts, infectious cysts, and other cystic neoplasms. Preoperative imaging, particularly abdominal MRI with MRCP, plays a key role in differentiating these entities which differ widely in management. Familiarity with the differentiating imaging features of mucinous cystic neoplasms and their mimics allows radiologists to provide management-guiding reports. Read More

CT and MRI features differentiating mucinous cystic neoplasms of the liver from pathologically simple cysts.

Clin Imaging 2021 Aug 3;76:46-52. Epub 2021 Feb 3.

Massachusetts General Hospital, Department of Radiology, 55 Fruit Street, Boston, MA 02114, USA. Electronic address:

Purpose: The purpose of this study was to determine if CT and MRI features can accurately differentiate mucinous cystic neoplasms (MCNs) from simple liver cysts and to compare accuracy of CT and MRI in detecting these features.

Methods: Eighty-four surgically treated lesions with pre-operative CT or MRI were evaluated by two abdominal radiologists for upstream biliary dilatation, perfusional change, internal hemorrhage, thin septations, thick septations/nodularity, lobar location, and number of coexistent liver cysts. Odds ratios, sensitivities, specificities, and positive and negative predictive values were calculated for association of each feature with MCNs. Read More

Atypic large hepatic cyst with persistent elevated CA19.9 serum value: utility of intracystic CA72.4 dosage for a mini-invasive management.

Clin J Gastroenterol 2021 Feb 20;14(1):258-262. Epub 2020 Nov 20.

Department of Digestive Surgery, CHU Amiens and University of Picardie, 1 rue du Professeur Christian Cabrol, 80054, Amiens cedex, France.

Simple hepatic cysts are very common, but may be difficult to differentiate from a biliary cystadenoma or cystadenocarcinoma. Because the surgical treatment if needed, such as a hepatic fenestration or resection, depends on the diagnosis, the assay of intracystic tumor markers is useful.We report the case of a 67-year-old woman with a large hepatic cyst responsible of pain and inflammation.

Hepatobiliary Mucinous Cystic Neoplasms With Ovarian Type Stroma (So-Called "Hepatobiliary Cystadenoma/Cystadenocarcinoma"): Clinicopathologic Analysis of 36 Cases Illustrates Rarity of Carcinomatous Change.

Am J Surg Pathol 2018 Jan;42(1):95-102

Department of Pathology, Medical College of Wisconsin Milwaukee, WI, USA.

The literature is highly conflicting on hepatobiliary mucinous cystic neoplasms (MCNs), aka "hepatobiliary cystadenoma/cystadenocarcinoma," largely because ovarian stroma (OS) was not a requirement until WHO-2010 and is not widely applied even today. In this study, MCNs (with OS) accounted for 24 of 229 (11%) resected hepatic cysts in one institution. Eight of the 32 (25%) cysts that had been originally designated as hepatobiliary cystadenoma/cystadenocarcinoma at the time of diagnosis proved not to have an OS during this review and were thus re-classified as non-MCN.

Rare biliary cystic tumors: a case series of biliary cystadenomas and cystadenocarcinoma.

Ann Hepatol 2016 May-Jun;15(3):448-52

Department of Gastroenterology, P.D. Hinduja National Hospital and Medical Research Centre, Veer Savarkar Marg, Mahim, Mumbai, Maharashtra, India.

Cystic lesions of the liver are common and a major proportion is formed by parasitic cysts and simple cysts. Biliary cystic tumors (BCTs), namely biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC), are rare tumors which usually arise from the intrahepatic biliary tree. BCAs have malignant potential and are difficult to differentiate from BCAC pre-operatively on radiological imaging. Read More
