Figure 22.

Primary hepatic lymphoma in a 72-year-old woman. The axial T2-weighted FS image (A) shows a moderately hyperintense lesion in liver segment II (arrow). Note also the biliary dilatation on the periphery of the lesion. In the plain T1-weighted image (B), the tumor (arrow) is hypointense with a slight enhancement in the arterial phase (C) and progressive central opacification in the portal venous (D) and delayed phases (E). A small satellite lesion is also seen (dashed arrow) in (B–E). Hematoxylin and eosin (H&E) staining showed non-Hodgkin liver lymphoma with T-cell histocyte-rich large B-cells (arrows). Remnants of biliary ductules are also shown (dashed arrow); original magnification ×40 (F).
