Primary hepatic non-Hodgkin lymphoma in a 55-year-old man with jaundice. a Gray-scale US image showing a large, well-defined, markedly hypoechoic lesion in the right lobe of liver (marked by calipers). CECT images (b-d) demonstrating a hypoenhancing lesion (asterisks) with arterial channels coursing through it (arrows in b and c). Changes of liver cirrhosis and ascites can also be seen with biliary dilatation (arrow in d). MR images reveal a homogeneous, mildly T2-hyperintense, diffusion restricting lesion (asterisk in e and f)
