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. Read More

Cystic neoplasms of the liver are rare tumours. According to the recent WHO classification, they are classified into mucinous cystic neoplasm and intraductal papillary neoplasm based on the presence of ovarian-like stroma and biliary communication. We report two rare cases of mucinous cystadenoma of the liver with biliary communication and discuss the shortcomings of current classification. Read More

A 33-year-old Thai born woman was referred to our tertiary referral hospital with back and epigastric pain. Investigations included abdominal ultrasound and CT scan of the abdomen which demonstrated a 3 cm cystic lesion in the head of the pancreas, most likely a mucinous cystadenoma. Because of its malignant potential resection was advised. Read More

We present a rare case of simultaneous occurrence of mucinous cystadenoma of the liver (MCN-L) and a hepatic hydatid cyst (HD-L) in a middle-aged female patient. This is the first case report of a common disease (HD-L) and a rare condition (MCN-H) occurring concurrently. MCN-H of the left lobe was inadequately resected in a rural centre leading to recurrence.

Hepatic mucinous cystic neoplasms represent a challenging pathology due to their very low frequency, insidious presentation and unclear demography due to the limited cases reported to date. Surgical treatment is mandatory when possible to prevent recurrence and malignant transformation. The case presented herein has a peculiarity, mainly an increased level of CA 19-9 which has not been previously reported. Read More

Background: Mucinous cystic neoplasm of the liver with extrahepatic growth is a rare benign epithelial neoplasm of the biliary system that presents with a mass effect or is incidentally found on imaging. The tumor affects mostly the common hepatic duct, which is difficult to diagnose preoperatively by radiology, endoscopy, or cystic fluid analysis. Endoscopic ultrasound is a noninvasive tool for the evaluation of features of a cystic lesion and the extent of disease. Read More

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.

Objective: To identify performance of imaging features in differentiating hepatic cysts from biliary cystadenomas of the liver.

Methods: 25 pathologically confirmed hepatic cystic lesions (hepatic cysts or biliary cystadenomas) were evaluated retrospectively and predetermined imaging features assessed for performance in differentiation.

Results: Any septation which arose from a cyst wall without external indentation had a very high association with biliary cystadenoma, while the presence of a thick septation had only a moderate association. Read More

Background: Intrahepatic biliary cystadenomas are rare hepatic neoplasms, which are usually cystic. These tumors are often misdiagnosed as simple liver cysts and hydatid cysts clinically and radiologically owing to nonspecific clinical and radiologic features. These tumors require complete resection, as recurrence and malignant transformation can occur following incomplete excision. Read More

Rationale: Glucagonoma and pancreatic serous oligocystic adenoma (SOA) are rare neuroendocrine and exocrine tumors of the pancreas, respectively. The coexistence of glucagonoma syndrome (GS) and SOA is a rare clinical condition and has not yet been reported. Additionally, necrolytic migratory erythema (NME), a hallmark clinical sign of GS, is often misdiagnosed as other skin lesions by clinicians due to their lack of related knowledge, which delays diagnosis of GS and thus exacerbates the prognosis.

Mucinous cystadenomas (MCAs) of the liver (also called hepatic biliary cystadenomas) are rare tumors that comprise about 5% of cystic masses of the liver in adults. These slow-growing lesions most commonly occur in middle-aged individuals, with a female sex predominance. Herein, we present a MCA in a 6-year-old male, one of only very few such cases described in the pediatric literature to date. Read More

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.

Introduction: Fast-growing congenital hepatic cysts with intracystic hemorrhage are rare in clinical practice. Additionally, the clinical manifestations of and laboratory and imaging findings for this condition are often nonspecific and are particularly difficult to differentiate from those of hepatobiliary cystadenoma and cystadenocarcinoma, thus posing great challenges for diagnosis and treatment. The 2 case reports presented here aim to analyze the diagnosis and treatment of 2 rare cases of congenital hepatic cysts with intracystic hemorrhage in the Chinese Han population to provide an important reference for the clinical diagnosis and treatment of this condition.

Objective: To explore the genes (biomarkers) correlated with cyst calcification in patients with cystic echinococcosis (CE), and to provide the evidence for the judgment on the patients' prognosis at molecular level.

Methods: The liver tissues from 32 patients with liver CE (10 cases for mRNA microarray and 22 cases for real-time PCR analysis) and 11 patients with hepatic cystadenoma were collected from three hospitals in Ningxia from June, 2013 to December, 2014.

Cholangiocarcinomas (CCAs) are anatomically classified into intrahepatic, perihilar, and distal types. The gross pathological classification of intrahepatic CCAs divides them into mass-forming, periductal-infiltrating, and intraductal-growth types; and perihilar/distal CCAs into flat- and nodular-infiltrating and papillary types. Unique preinvasive lesions appear to precede individual gross types of CCA. Read More

We describe two cases of MCN-L that exhibited extremely interesting growth patterns, and discuss the characteristics of MCN-Ls.

Most malignant liver tumors are represented by hepatocellular carcinoma and cholangiocarcinoma; however a variety of other uncommon hepatic lesions might also be found. Common lesions such as hemangioma, focal nodular hyperplasia and metastases are well known and have already been extensively documented in the literature. The diagnosis of typical hepatic lesions may be done with some reliability by means of several imaging methods; on the other hand, uncommon lesions normally represent a diagnostic challenge for the radiologist.
