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.

Sally Griffin

J Feline Med Surg 2019 01;21(1):12-24

Radiology Department, Willows Veterinary Centre and Referral Service, Highlands Road, Shirley, Solihull B90 4NH, UK.

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

Cyst-forming intraductal papillary neoplasm of the bile ducts: description of imaging and pathologic aspects.

AJR Am J Roentgenol 2011 Nov;197(5):1111-20

Department of Radiology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Gangnam-gu, Seoul, Republic of Korea.

Objective: Intraductal papillary neoplasm (IPN) of the bile duct is a newly described pathologic entity characterized by the presence of intraluminal tumors, which sometimes produce a large amount of mucin and form a cystic tumor. Cystic IPN of the bile duct is different from biliary cystadenoma or cystadenocarcinoma in that the former produces intraductal microscopic and macroscopic papillary tumors without ovarian-like stroma, whereas the latter produce a mucin-containing septate cystic tumor without communication with bile duct and with ovarian-like stroma in the cyst wall. The purpose of this study was to evaluate the potential relationships between cyst-forming IPNs of the bile duct and peribiliary glands and also intraductal papillary mucinous neoplasms of the pancreas.

Service d'anatomie pathologique, groupe hospitalier Paul-Brousse-Bicêtre, AP-HP, Le Kremlin-Bicetre, France.

Intrahepatic biliary cysts encompass a large lesional spectrum including hereditary diseases as polycystic liver disease or Caroli's syndrome, malformative lesions as non hereditary Caroli's disease or simple biliary cyst and true neoplastic lesions as cystadenoma or cystadenocarcinoma. The diagnostic approach of these lesions relies firstly on imaging. Nevertheless, the pathologist not exceptionally receives surgical specimens from cystic fenestration or liver specimen resection with one or several cystic lesions. Read More

Conventional ultrasound (US) is the first-line imaging investigation for biliary diseases. However, it is lack of the ability to depict the microcirculation of some lesions which may lead to failure in diagnosis for some biliary diseases. The use of contrast-enhanced US (CEUS) has reached the field of bile duct disease in recent years and promising results have been achieved. Read More
