hepatic lymphoma

Hepatic lymphoma is a term given to any form of hepatic involvement with lymphoma. This can be broadly divided into:

Pathology

Risk factors for developing hepatic lymphoma:

  • HIV/AIDS (25-46%)
  • hepatitis C (HCV) mostly in patients with non-Hodgkin’s lymphoma (15%)
  • organ transplantation (2-12%)
  • immunosuppression 

Radiographic features

Many tend to present as focal liver lesions . It may be difficult to differentiate primary vs. secondary from analysis of the liver lesion alone (at the time of initial writing).

CT

Lesions are reported to be hypoattenuating on CT .

MRI

Reported signal characteristics include :

  • T1: hypointense (mild to moderate) relative to liver
  • T2: hyperintense relative to liver
  • C+ (Gd): transient increased perilesional enhancement is common
