Abstract A 55-year-old male had surgery for colon cancer in December 2017. A mass was found in the right posterior lobe of his liver in January 2019. There was no previous history of hepatitis, and all tumor markers were within normal ranges. Ultrasound examination found a 2.0 × 1.7 cm hypoechoic nodule with unclear boundaries and regular shape in hepatic segment VII. Contrast-enhanced ultrasound (CEUS) displayed hyperenhancement in the arterial phase and wash-out in the early portal phase, and the delayed phase was hypoenhanced (Fig. 1 ). Contrast-enhanced computed tomography (CECT) presented a 1.5 cm slightly enhanced hepatic mass in the arterial phase and rim-enhancement in the portal phase (Fig. 2 A-C). Magnetic resonance imaging (MRI) showed high intensity on T2W fat-suppressed scan and peripheral hyperintensity on contrast-enhanced T1W portal phase with no uptake of the contrast agent during the delayed phase (Fig. 2 D-F), and diffusion weight was restricted in the right posterior upper hepatic segment. Preoperative diagnosis was metastatic carcinoma of the liver.
