Axial CT images axial contrast-enhanced CT image and liver ultrasound of a patient with HIV-associated primary hepatic lymphoma. The contrast-enhanced CT shows a homogeneous soft tissue attenuation mass which does not show significant enhancement, and with fear preservation of the surrounding liver architecture. The mass displaces or encases the hepatic veins but does not invade vasculature or lead to tumor thrombus. On ultrasound, it appears as a fairly homogenous mass hypoechoic to the liver parenchyma. There is no increase vascularity within the mass or in its periphery
