Introduction Percutaneous thermal ablation of inconspicuous lesions can be challenging. Fusion ultrasound (FUS) allows the use of previously performed diagnostic imaging like computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET–CT) to localise hepatocellular carcinoma (HCC) for treatment. This paper illustrates FUS case studies of pre-, intra- and post-ablation imaging of inconspicuous HCC, supplemented by use of contrast-enhanced ultrasound (CEUS). Method Four prospective cases during September 2014 to October 2018, with HCC amenable to ablation, which were poorly identified on ultrasound, underwent FUS. FUS pre-screening was scheduled within three months of the previous CT or MRI, and between one to four weeks prior to the scheduled ablation date. Post-ablation imaging with FUS was performed between four to six weeks to coincide with their routine follow-up CT or MRI. Findings There were potential benefits observed in the cases with combined techniques of FUS and CEUS for limiting circumstances such as heat sink effect, multiple lesions targeting, inconspicuous lesion detection and pre-ablation technical feasibility assessment. Discussion The combined use of FUS and CEUS improves tumour visibility, increases operator imaging confidence and reduces heat sink effect during percutaneous thermal ablation. Conclusion FUS imaging is helpful in targeting poor conspicuity lesions that cannot be detected on grey-scale ultrasound. It facilitates in ensuring optimal treatment of hepatic lesions for improvement of patient prognosis and follow-up imaging.

AbstractHepatocellular carcinoma (HCC) commonly affects patients with cirrhosis. Patients with early-stage disease may be treated with surgery, liver transplantation, and locoregional therapy (e.g., thermal ablation and chemoembolization). The treatment efficacy of thermal ablation can be limited by factors such as proximity to adjacent vessels, which may create a heat sink effect. The heat sink effect can be mitigated by intravascular balloon occlusion. Our case report demonstrates the utility of balloon occlusion during thermal ablation of HCC adjacent to the right hepatic vein complicated by hepatic vein thrombosis.
