Contrast-enhanced CT abdomen. (a) Early arterial phase showing a hypodense lesion in the left liver lobe and a normal spleen. (b) Venous phase showing a hypodense lesion confined to the left liver lobe and firmly attached to the middle hepatic vein. (c) A mixed-enhanced pattern of the lesion on the delayed phase.

A triple-phase contrast-enhanced CT abdomen depicted a 14 x 14 cm well-defined left liver lobe mass, involving segments II, III, and VI-A and VI-B, which was hypodense in the early arterial phase, retaining the contrast in the venous phase, and showing a mixed-enhanced pattern in the delayed phase (Figures 1(a)-1(c)).
An operative image shows a normal right liver lobe, and a well-demarcated mass arising from the left lobe was resected (vertical arrow).

A well-demarcated mass was palpated in the left lobe of the liver as characterized on CT scan (Figure 2).
(a) Hepatic infiltration with lymphoid cells (a population of dark blue-rounded cells:vertical red arrow) (H&E-stained slide (x20)). (b) Uniform sheet of round B-lymphoid cells (vertical red arrow) (H&E-stained slide (x100)).

Histopathology revealed a hepatic infiltration with lymphoid B-cells consistent with primary hepatic diffuse large B-cell lymphoma (DLBCL) with negative resection margins (Figures 3(a) and 3(b)).
