MRI for characterization of benign hepatocellular tumors on hepatobiliary phase: the added value of in-phase imaging and lesion-to-liver visual signal intensity ratio.

Eur Radiol 2019 Apr 16. Epub 2019 Apr 16.

Department of Gastrointestinal Imaging, Lille University Hospital, Rue Michel Polonovski, 59037, Lille Cedex, France.

Objectives: To evaluate the lesion-to-liver visual signal intensity ratio (SIR) before and at the hepatobiliary phase MRI (HBP-MRI) after gadobenate dimeglumine (Gd-BOPTA) injection, using several T1-weighted images (T1-WI), for the characterization of benign hepatocellular lesions.

Methods: Patients with histologically proven focal nodular hyperplasia (FNH) and hepatocellular adenoma (HCA), who underwent Gd-BOPTA-enhanced HBP-MRI from 2009 to 2017, were retrospectively identified. The lesion-to-liver SIR was visually assessed by two radiologists on HBP (post-HBP analysis) and compared with that of unenhanced sequences (pre/post-HBP analysis) on T1-WI in-phase (T1-IP), out-of-phase (T1-OP), and fat suppression (T1-FS).

Utilization of spectrins βI and βIII in diagnosis of hepatocellular carcinoma.

Ann Diagn Pathol 2019 Feb 15;39:86-91. Epub 2019 Feb 15.

Department of Pathology, Montefiore Medical Center, Albert Einstein College of Medicine, Bronx, NY 10467, United States of America. Electronic address:

Spectrins are a group of cytoskeletal proteins which participate in many important cellular functions. It has been suggested that loss of spectrin isoforms may be associated with tumorigenesis of lymphoma, leukemia, gastric cancer and hepatocellular carcinoma (HCC). We recently reported that βI spectrin expression was present in normal hepatocytes but lost in HCC cells, which suggested that spectrins may be helpful markers in diagnosis of HCC. Read More

Problematic lesions in cirrhotic liver mimicking hepatocellular carcinoma.

Eur Radiol 2019 Feb 20. Epub 2019 Feb 20.

Department of Radiology, Research Institute of Radiological Science, Severance Hospital, Yonsei University College of Medicine, 50-1 Yonsei-ro, Seodaemun-gu, Seoul, 03722, South Korea.

Hepatocellular carcinoma (HCC) is a unique malignancy that can be diagnosed and treated based on non-invasive imaging criteria without histological confirmation in cirrhotic patients, which opens the possibility, although rare, of false-positive diagnosis of the tumor. This brief review illustrates benign and non-HCC malignant lesions arising in cirrhotic liver that could have been erroneously diagnosed as HCC based on imaging criteria: focal nodular hyperplasia-like nodules, serum amyloid A-positive nodules, dysplastic nodules, spontaneously regressing lesions, combined hepatocellular-cholangiocarcinoma, cholangiocarcinoma, sarcomatoid carcinoma, lymphoepithelioma-like carcinoma, hepatoblastoma, and metastatic adenocarcinoma. To determine the potential differences in clinical courses and post-treatment outcome of HCC diagnosed by imaging alone and those histologically, we suggest the terms HCCi and HCCp to distinguish between lesions that are diagnosed as HCC based on imaging alone from those diagnosed based on pathological examination, respectively.

MicroRNA Expression in Focal Nodular Hyperplasia in Comparison with Cirrhosis and Hepatocellular Carcinoma.

Pathol Oncol Res 2018 Nov 9. Epub 2018 Nov 9.

2nd Department of Pathology, Semmelweis University, Ulloi 93, Budapest, H-1091, Hungary.

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

This is a rare case of a patient simultaneously presenting with five complications associated with the prolonged (5 years) use of combined oral contraceptives. The two main ingredients of combined oral contraceptives responsible for thromboembolism are estrogen (estradiol) and progestogen (progestin). Progestins are linked with occlusion of arteries while estrogens can induce both arterial and venous thrombosis. Read More

Heterogeneity of Fibrosis in Liver Biopsies of Patients With Heart Failure Undergoing Heart Transplant Evaluation.

Am J Surg Pathol 2018 Dec;42(12):1617-1624

Department of Pathology and Laboratory Medicine, Cedars-Sinai Medical Center.

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

Gastric Cancer Screening in Common Variable Immunodeficiency.

J Clin Immunol 2018 Oct 15;38(7):768-777. Epub 2018 Sep 15.

Faculty of Medicine, The University of Sydney, Sydney, NSW, Australia.

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.

OATPB1/B3 and MRP3 expression in hepatocellular adenoma predicts Gd-EOB-DTPA uptake and correlates with risk of malignancy.

Liver Int 2019 Jan 8;39(1):158-167. Epub 2018 Oct 8.

Service of Clinical Pathology, Institute of Pathology, Lausanne University Hospital, Lausanne, Switzerland.

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.
