Diffusion-weighted imaging might be useful for reactive lymphoid hyperplasia diagnosis of the liver: A case report

Figure 2 Magnetic resonance imaging of a 54-year-old woman with reactive lymphoid hyperplasia (arrow). A: T1-weighted in-phase image showed the hypointense lesion on liver segment 1; B: The lesion was a hyperintensity on fat-saturated T2-weighted image; C: The lesion had obvious hyperintensity on diffusion-weighted imaging. On serial imaging in diffusion-weighted imaging (numbered in order from the head direction), there was linear hyperintensity along the portal tract (arrowheads) consecutive to the liver lesion; D: The lesion showed perinodular enhancement in the arterial phase on gadoxetic acid–enhanced magnetic resonance imaging; E: The lesion showed washout in the portal phase; F: The lesion showed low signal intensity in the hepatobiliary phase.
