A 30-year-old woman presented with severe abdominal pain and abdominal distension. CT demonstrated two intra-abdominal masses, one involving the left lateral segment of the liver and the other adjacent to the duodenum. Initial biopsies were consistent with focal nodular hyperplasia of the liver and non-specific lymphocytic infiltrate in the paraduodenal mass. Read More

High body mass index (BMI) is associated with other multiple comorbidities such as non-alcoholic fatty liver disease, steatohepatitis, liver cirrhosis, and cardiopulmonary diseases, which can impact the perioperative outcomes following liver resection. We aimed to study the impact of BMI on perioperative outcomes after robotic liver resection. All the patients undergoing robotic liver resection between 2013 and 2017 were prospectively followed.

Gadoxetic acid, a hepatocyte-specific magnetic resonance imaging (MRI) contrast agent, has emerged as an important tool for hepatocellular carcinoma (HCC) diagnosis. Gadoxetic acid-enhanced MRI is useful for the evaluation of earlystage HCC, diagnosis of HCC precursor lesions, and highly sensitive diagnosis of HCC. Furthermore, functional information provided by gadoxetic acid-enhanced MRI can aid in the characterization of focal liver lesions. Read More

Many advances have developed in the pathology of liver tumors in the recent decade. Examples of these advances include the use of glutamine synthetase in the diagnosis of focal nodular hyperplasia, subtyping of hepatocellular adenomas using molecular and immunohistochemical methods, the unraveling of the fusion transcript between the DNAJB1 gene and the PRKACA gene in fibrolamellar carcinoma, and the more unified classification and terminology in intrahepatic bile duct tumors and their precursor lesions.

It is uncertain whether thymic neuroendocrine tumors (NET) associated with Cushing's syndrome (CS) produce corticotropin-releasing hormone (CRH) and adrenocorticotropin hormone (ACTH) and whether the thymus contains ACTH and/or CRH cells that could originate NET. The clinicopathologic features of 5 typical (TC) and 6 atypical carcinoids (ATC), 10 additional non-neoplastic thymi, 6 adrenal glands with bilateral nodular hyperplasia and 8 adrenal cortical adenomas were reviewed. Representative slides were immunostained for ACTH and CRH. Read More

A 7-year-old patient with a stage 4 neuroblastoma underwent chemotherapy, surgery, myeloablative therapy, external beam radiotherapy, and Isoretinoin treatment. A posttreatment magnetic resonance examination performed administering gadoteric acid as contrast agent showed 2 new hypervascular hepatic lesions, suspicious for metastases. A second magnetic resonance imaging performed using a liver-specific contrast medium (gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid) demonstrated that these lesions were consistent with treatment-related focal nodular hyperplasia.

Focal nodular hyperplasia (FNH) is the second most common liver cell-derived benign tumor. It is postulated that chemotherapy-induced hepatic circulatory abnormalities, like sinusoidal obstruction syndrome (SOS), could lead to the development of FNH. Cyclophosphamide was also reported to induce SOS in a synergistic effect with total body irradiation. Read More

The liver disease focal nodular hyperplasia (FNH) has several histological features that resemble hepatic cirrhosis. Since cirrhosis may develop further into hepatocellular carcinoma (HCC) contrary to FNH, the aim of the present study was to identify microRNAs (miRNA), which, by their altered expression levels, may be associated with the benign, tumor-like nature of FNH. Altogether 106 surgically removed formalin-fixed paraffin-embedded liver samples were selected, including 22 FNH, 45 cirrhosis, 24 HCC and 15 normal liver tissues. Read More

Liver biopsies are commonly performed in heart transplant candidates to confirm congestive hepatopathy (CH) and to assess the degree of fibrosis. Heterogeneity of fibrosis is frequent in CH, making it difficult to stage fibrosis. In this study, we evaluated the prevalence of heterogeneity of fibrosis and nodular regenerative hyperplasia (NRH) in liver biopsies with CH secondary to heart failure. Read More

Individuals with common variable immunodeficiency (CVID) have an increased risk of gastric cancer, and gastrointestinal lymphoma, yet screening for premalignant gastric lesions is rarely offered routinely to these patients. Proposed screening protocols are not widely accepted and are based on gastric cancer risk factors that are not applicable to all CVID patients. Fifty-two CVID patients were recruited for screening gastroscopy irrespective of symptoms or blood results and were compared to 40 controls presenting for gastroscopy for other clinical indications.

Background And Aims: Hepatobiliary phase (HBP) Gd-EOB-DTPA-enhanced magnetic resonance imaging (MRI) has increased the accuracy in differentiating focal nodular hyperplasia (FNH) and hepatocellular adenoma (HCA). However, the ability of this technique to distinguish HCA subtypes remains controversial. The aim of this study was to investigate the expression of hepatocyte transporters (OATPB1/B3, MRP2, MRP3) in HCA subtypes, hence to understand their MRI signal intensity on HBP Gd-EOB-DTPA-enhanced MRI.

Methods: 94 hepatic focal lesions, including 38 HCC, 16 metastasis, 12 focal nodular hyperplasia, 13 cholangiocarcinoma, and 15 hemangioma, were examined in this study. Diffusion-weighted images were acquired with 13 b values (b = 0, 3, …, 500 s/mm) to measure the adaptive multi-exponential IVIM parameters, namely, pure diffusion coefficient (D), diffusion fraction (f), pseudo-diffusion coefficient (D*) and perfusion-related diffusion fraction (f) of the ith perfusion component.

Hepatocyte-specific contrast media are gadolinium chelates that are taken up by hepatocytes and partially cleared via the biliary tree. The absence of lesional uptake of the contrast media in the hepatobiliary phase is a marker of either the absence of hepatocytes or of poorly functioning, neoplastic hepatocytes. Uptake of the contrast media in the hepatobiliary phase, whether equal to or greater than background liver, reflects the presence of hepatocytes but does not equate to absence of neoplasia.

Magnetic resonance imaging (MRI) is commonly used to characterize focal liver masses in the pediatric population. MRI is the preferred modality because of its superior contrast resolution and utility for obtaining functional sequences such as diffusion-weighted imaging (DWI). MR exams performed with a hepatocyte-specific gadolinium-based contrast agent can characterize focal liver lesions, which helps in differentiating a common benign entity such as focal nodular hyperplasia from other liver pathology when the background liver is normal.

Liver vascular malformations (VMs) in hereditary hemorrhagic telangiectasia (HHT) are typically diffuse and can evolve from small telangiectasias to large arteriovenous malformations, with various stages of severity. Doppler US is the ideal first-line investigation for the assessment of liver VMs in HHT due to its safety, tolerability, low costs, and accuracy for the detection of liver VMs. The caliber, course, and flow characteristics in the hepatic artery, portal vein, and hepatic vein as determined by Doppler US, together with parenchymal abnormalities, support the diagnosis of liver VMs in HHT and their severity staging.
