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

Figure 3 Pathological findings and diffusion-weighted imaging of reactive lymphoid hyperplasia on liver segment 8. A: Hematoxylin and eosin stain (20 ×). Histologically, there was dense lymphoplasmacytic infiltration in the subserosa region of the liver (segment 8), forming various-sized lymphoid follicles with enlarged germinal centers; B: Hematoxylin and eosin stain (100 ×). These cells did not invade into the hepatic lobules, and the limiting plates were preserved; C: Hematoxylin and eosin stain (20 ×). At the peripheral site of the lesion, lymphoplasmacytic infiltration extended along the portal tracts in a radial pattern; D: Elastica van Gieson stain (20 ×). There was no definite evidence of portal venular stenosis or fibrosis; E: Diffusion-weighted imaging showed the lesion corresponding to this pathologically presented lesion. There was linear hyperintensity along the portal tract close to the liver lesions (arrow).
