Mucinous liver metastasis in a 53-year-old male. The 60 mm mucinous lesion located in the right liver lobe shows high signal intensity on diffusion weighted image (b 600 s/mm²) (a) with high apparent diffusion coefficient values (b) and high signal intensity on fat-saturated fast spin echo T2-weighted image (c). There is mild peripheral (arrow) and inner enhancement on extracellular gadolinium chelate-enhanced fat-saturated gradient recall echo (GRE) T1-weighted image obtained during the portal venous phase (d). Note the thin layer of low apparent diffusion coefficient values at the periphery of the tumor (b—arrowhead), corresponding to the enhancing areas. Gross pathology (e) and histological analysis (f) confirmed the mucinous subtype. Note the pools of extracellular mucin within the tumor (T) well-separated from the rest of the liver parenchyma (Li), which is displaced
