Hepatic lymphoma is a term given to any form of hepatic involvement with lymphoma. This can be broadly divided into:
- secondary hepatic involvement with lymphoma: most common by far, many tend to be non-Hodgkin lymphoma (NHL)
- primary hepatic lymphoma: extremely rare
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
