Successful Surgical Management of Giant Mucinous Cystic Neoplasm of Liver (MCN-L) Presenting With Peritoneal Rupture and Biliary Prolapse: Case Report and Review of Literature.

Mucinous cystic neoplasms of liver (MCN-L) are generally considered benign indolent cystic liver lesions, not associated with significant clinical symptoms in majority of patients. However, rarely these benign-appearing lesions may have a complicated clinical course, presenting with jaundice, acute abdomen, or malignant transformation. We report one such rare clinical presentation of MCN-L presenting with obstructive jaundice and abdominal pain due to prolapse of cystic component in biliary system and peritoneal rupture occurring simultaneously.

Mucinous Cystic Neoplasms of the Liver: Epidemiology, Diagnosis, and Management.

Mucinous cystic neoplasms (MCNs) are rare tumors of the liver, occasionally seen in the biliary tree. Epidemiologic data are limited by their indolence and recent changes to diagnostic criteria. They are considered premalignant lesions capable of invasive behavior.

Cystadenocarcinoma of the gallbladder: A case report.

Introduction And Importance: Cystadenoma and cystadenocarcinoma of the biliary duct remain a rare diagnosis, the localization is intrahepatic in 97% of the cases and extrahepatic in 3%of them [1]. Cystadenocarcinoma of the gallbladder is the rarest localization, it's usually diagnosed late because of the poor symptoms and the nonspecific lesions in the different imaging.Only hundreds of cases have been reported for cystadenocarcinoma of the gallbladder.

Cystadenocarcinoma of the intrahepatic bile duct in a dog.

A 14-year-old spayed female Shih-Tzu was referred to the Veterinary Medical Teaching Hospital of Konkuk University for evaluation of an abdominal mass. In diagnostic imaging, two large cystic masses were identified. The affected liver lobes were surgically resected, and the specimens were submitted for histopathological evaluation and immunohistochemical staining.

Sequential thermal ablation in combination with sclerotherapy using lauromacrogol as a successful translative therapy for an unresectable huge biliary cystadenocarcinoma: The first experience assisted by contrast-enhanced ultrasound.

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).

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

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.

Hepatobiliary mucinous cystic neoplasms and mimics.

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.

Enucleation of Biliary Cystadenomas: a Review.

Background: Biliary cystadenomas are very rare benign tumors which can transform into cystadenocarcinomas. The largest case series reported on 221 cases over 30 years from 10 HPB centers, i.e.

A rare case of extrahepatic biliary mucinous cystic neoplasm in a middle-aged woman: A case report.

Biliary mucinous cystic neoplasms are very rare tumors of the biliary tract with malignant potential. Preoperative diagnosis is challenging, as clinical, biochemical and radiological features are not specific. Surgical resection with negative margins is the gold standard treatment for these uncommon lesions.

MRI is useful to suggest and exclude malignancy in mucinous cystic neoplasms of the pancreas.

Objectives: To evaluate the value of MRI in differentiating benign (b-MCN) and malignant (m-MCN) MCN. European guidelines suggest that certain mucinous cystic neoplasms (MCN) of the pancreas can be conservatively managed.

Methods: A retrospective single-center study of consecutive patients with resected MCN.

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

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.

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

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.

Contemporary Management of Hepatic Cyst Disease: Techniques and Outcomes at a Tertiary Hepatobiliary Center.

Background: Hepatic cyst disease is often asymptomatic, but treatment is warranted if patients experience symptoms. We describe our management approach to these patients and review the technical nuances of the laparoscopic approach.

Methods: Medical records were reviewed for operative management of hepatic cysts from 2012 to 2019 at a single, tertiary academic medical center.

Cystic lymphangioma of the hepatoduodenal ligament: a rare intra-abdominal tumor mimicking hematoma.

A 22-year-old man was referred for upper abdominal pain. Unenhanced computed tomography (CT) revealed a lesion of heterogeneous hypoattenuation, part of which showed slightly high-density in the porta hepatis. On magnetic resonance imaging (MRI), T1-weighted images showed a multiloculated hyperintense mass and part of the mass was hyperintense in T2-weighted images.

Biliary Mucinous Cystadenoma: A Review of the Literature.

Biliary mucinous cystadenomas are cystic neoplasms commonly mistaken for simple cysts. They are rare and generally benign tumors, often incidentally found on imaging and during unrelated surgical interventions. They tend to be slow growing though may reach symptomatic dimensions.

The impact of imaging on the surgical management of biliary cystadenomas and cystadenocarcinomas; a systematic review.

Background: Biliary Cystadenomas (BCA) are considered to be benign but may transform to Biliary Cystadenocarcinomas (BCAC). The aim of this systematic review was to assess the diagnostic work-up and necessity of complete surgical resection.

Method: A systematic literature search was performed in Embase.

Feline abdominal ultrasonography: what's normal? what's abnormal? The liver.

Practical Relevance: Abdominal ultrasound plays a vital role in the diagnostic work-up of many cats presenting to general and specialist practitioners. Ultrasound examination of the liver can be key in the diagnosis of diseases such as hepatic lipidosis and hepatic neoplasia.

Clinical Challenges: Despite ultrasonography being a commonly used modality, many practitioners are not comfortable performing an ultrasound examination or interpreting the resulting images.

Spectrum of hepatobiliary cystic lesions: A 7-year experience at a tertiary care referral center in North India and review of literature.

Context: Cysts arising from the hepatobiliary tree are a group of heterogeneous lesions with regard to pathogenesis, clinical presentation, and radiological finding. They can be intrahepatic or extrahepatic, developmental, secondary to infective/inflammatory etiologies, as well as neoplastic. This study was conducted to determine the spectrum of hepatobiliary cysts in surgically intervened cases, with regard to their prevalence, histological spectrum, and clinicoradiological correlation, wherever possible.

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

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.

Clinicopathological features and post-resection outcomes of biliary cystadenoma and cystadenocarcinoma of the liver.

Backgrounds/aims: Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCAC) account for 5%-10% of liver cystic diseases. In this study, we analysed the clinical presentation and surgical management of patients with BCA and BCAC.

Methods: We retrospectively analysed the medical records of 23 BCA and 7 BCAC cases diagnosed between January 2007 and December 2013.
