Medical imaging plays an important role in the diagnosis and management of hepatocellular carcinoma (HCC). The Liver Imaging Reporting and Data System (LI-RADS) was initially created to standardize the reporting and data collection of CT and MR imaging for patients at risk for HCC. As contrast-enhanced ultrasound (CEUS) has been widely used in clinical practice, it has recently been added to the LI-RADS. While CEUS LI-RADS shares fundamental concepts with CT/MRI LI-RADS, there are key differences between the modalities reflecting dissimilarities in the underlying methods of image acquisition and types of contrast material...

A 66-year-old man with history of prostate carcinoma underwent Ga-labeled prostate-specific membrane antigen PET/CT for surveillance of rising prostate-specific antigen. Intense tracer uptake was noted in segments 2, 7, and 8 of the liver. The lesions were not FDG avid on F-FDG PET/CT. Further characterization with magnetic resonance cholangiopancreatography with Gd-EOB (Primovist) contrast revealed ill-defined arterially enhancing lesions with central washout in the venous phase. CT-guided core biopsy was performed, and histopathology confirmed well-differentiated hepatocellular carcinoma...

18F-FDG has low uptake and poor diagnostic efficiency in hepatocellular carcinoma (HCC), particularly in well-differentiated HCC. The NGR peptide selectively targets CD13, which is overexpressed in many types of tumor cells as well as neovasculature cells. In the present study, we aimed to evaluate the feasibility of utilizing 68Ga-NGR to image CD13-positive well-differentiated HCC xenografts. The in vitro cellular uptake, in vivo micro-PET/CT imaging and biodistribution studies of 68Ga-NGR and 18F-FDG were quantitatively compared in SMMC-7721-based well‑differentiated HCC xenografts...

While cross-sectional imaging with computed tomography (CT) and magnetic resonance imaging is the primary method for diagnosing hepatocellular carcinoma (HCC), they provide little biological insight into this molecularly heterogeneous disease. Nuclear imaging tools that can detect molecular subsets of tumors could greatly improve diagnosis and management of HCC. To this end, we conducted a patient study to determine whether HCC can be resolved using (68)Ga-citrate positron emission tomography (PET). One patient with recurrent HCC was injected with 300 MBq of (68)Ga-citrate and imaged with PET/CT 249 minutes post injection...

BACKGROUND/PURPOSE: The pattern of tumor cell spread via the portal system has not been fully clarified in patients with hepatocellular carcinoma (HCC). This study aimed to evaluate the intrahepatic distribution of cancer cells derived from the main tumor by assessing histological portal invasion and/or intrahepatic metastasis (vp/im). METHODS: In 14 patients who underwent anatomical resection of primary solitary HCC ≤ 50 mm in diameter, vp/im were examined pathologically, and the sites of the lesions were reproduced on preoperative 3D-CT images...

Multiphasic computed tomography (CT) and magnetic resonance imaging (MRI) are both used for non-invasive diagnosis of hepatocellular carcinoma (HCC) in patients with cirrhosis. To determine if there is a relative diagnostic benefit of one over the other, we synthesized evidence regarding the relative performances of CT, extracellular-contrast-enhanced-MRI, and gadoxetate-enhanced-MRI for diagnosis of HCC in patients with cirrhosis. We also assessed whether liver biopsy versus follow-up with the same versus alternative imaging is best for CT- or MRI-indeterminate liver nodules in patients with cirrhosis...

Comprehensive treatments together with sorafenib provide a survival benefit for patients with advanced hepatocellular carcinoma (HCC). Acute-on-chronic liver failure (ACLF) is an increasingly recognized distinct entity; however, only few cases induced by sorafenib have been reported to date. We herein present a rare case of ACLF in a patient under treatment with sorafenib. A 63-year-old woman who suffered from hepatitis B for 10 years was admitted to our hospital. A computed tomography (CT) scan led to a diagnosis of HCC in the V/VIII hepatic segment, with invasion of the middle hepatic and the right portal veins...

Identification of extrahepatic metastases (EHM) of hepatocellular carcinoma (HCC) has been paradoxically increasing due to an increase in the survival of HCC patients. However, metastasis of HCC to the skeletal muscle tissue is extremely rare. We describe a unique case of HCC metastasizing to the paravertebral muscle. A 55-year-old man with a history of hepatitis B cirrhosis underwent partial liver resection with complete removal of HCC. Three months later, a computed tomography (CT) scan showed intrahepatic recurrence...

Peripheral T-cell lymphomas (PTCLs) are aggressive neoplasms which may involve the liver. The imaging manifestations of hepatic lymphoma are highly variable and show overlapping appearances of numerous other hepatic diseases. As the management and prognosis of lymphoma differ markedly from those of other malignant diseases, prompt diagnosis and early effective treatment are very important. Here, we report an atypical case of primary PTCL not otherwise specified involving the liver that exhibited a solitary hepatic mass mimicking hepatocellular carcinoma (HCC) on CT...

The Liver Imaging Reporting and Data System (LI-RADS) was designed to standardize the interpretation and reporting of observations seen on studies performed in patients at risk for development of hepatocellular carcinoma (HCC). The LI-RADS algorithm guides radiologists through the process of categorizing observations on a spectrum from definitely benign to definitely HCC. Major features are the imaging features used to categorize observations as LI-RADS 3 (intermediate probability of malignancy), LIRADS 4 (probably HCC), and LI-RADS 5 (definite HCC)...

INTRODUCTION: The lung is the most common site of distal metastasis in patients with hepatocellular carcinoma (HCC), as seen in more than half of patients with extrahepatic disease. The incidence of pulmonary metastasis in all patients with HCC, however, remains low (between 4.5% to 20%). Their presence, nevertheless, contraindicates curative locoregional therapies. The role of staging chest computed tomography (CT) before locoregional treatment is not well defined. This study aimed to assess the utility of pre-treatment chest CT prior to locoregional therapy...
