Can Contrast Enhanced Ultrasound Differentiate Intrahepatic Cholangiocarcinoma From Hepatocellular Carcinoma?, Jia-Yan Huang, Jia-Wu Li, Wen-Wu Ling, Tao Li, Yan Luo, Ji-Bin Liu, Qiang Lu

Department of Radiology Faculty Papers

BACKGROUND: Hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) differ in treatment and prognosis, warranting an effective differential diagnosis between them. The LR-M category in the contrast-enhanced ultrasound (CEUS) liver imaging reporting and data system (LI-RADS) was set up for lesions that are malignant but not specific to HCC. However, a substantial number of HCC cases in this category elevated the diagnostic challenge.

AIM: To investigate the possibility and efficacy of differentiating ICC from HCC classified in the LR-M category according to the CEUS LI-RADS.

METHODS: Patients with complete CEUS records together with pathologically confirmed ICC and LR-M HCC (HCC classified …

Lung Metastasis Postradioembolization Of Hepatocellular Carcinoma With Tumor In Vein, Harit Kapoor, Sreeja Sanampudi, Joseph W. Owen, Driss Raissi

Radiology Faculty Publications

Transarterial radioembolization (TARE) is one of the few treatment options available for infiltrative hepatocellular carcinoma with tumor in vein. This is backed by the published data showing marginally favorable toxicity profile compared with other locoregional and systemic therapies. Although lung shunt fraction studies are performed to prevent radiation injury to the lungs, TARE-induced embolization/metastasis to the lungs has not been reported before. We report an intriguing case of new lung metastases within 1 month after TARE for infiltrative hepatocellular carcinoma with a tumor in the vein, with only a slightly elevated but acceptable lung shunt fraction. This report brings to …

Hepatocellular Carcinoma Treated With Microwave Ablation Prior To Liver Transplantation, Nicole Wagner, Amanda Smolock, Michael Markovitz, Varun Danda, Christopher Neely, Warren Maley, Jesse Civan, Colette Shaw

Phase 1

Introduction: Ablation is a minimally invasive procedure that limits local liver tumor progression and prolongs patients’ transplantation eligibility. Microwave ablation (MWA) utilizes higher temperatures than the standard of care, radiofrequency ablation (RFA), which increases efficiency. Meta-analyses compared MWA with RFA for the treatment of HCC and showed similar efficacy and safety between these modalities. However, limited pathologic data exists determining whether explanted tumors remained viable after MWA.

Methods: Our database was reviewed retrospectively for patients with HCC who underwent MWA prior to liver transplantation between 2013 and 2019. Patient demographics, etiology of disease, tumor size, procedure details, bilirubin, MELD, …
