Example of mucinous metastasis mimicking a hemangioma in 45-year-old male patient with colon cancer. Fat-saturated fast spin echo T2-weighted image (a) shows a 30 mm lesion (arrow) in segment VIII with bright signal intensity. The lesion shows peripheral rim enhancement (arrow) on extracellular gadolinium chelate-enhanced fat-saturated gradient recall echo T1-weighted image obtained during the portal venous phase (b). Arterial phase, contrast-enhanced ultrasound (c) shows rapid homogeneous enhancement at 14 s (arrow). At 20 s (d), the lesion shows washout (arrow), consistent with a diagnosis of liver metastasis
