Certain clinical and imaging findings can identify a liver that is involved by malignant lymphoma. The criteria were developed at the 12th International Conference (2013) for Malignant Lymphoma in Lugano, Switzerland.

Patient selection: malignant lymphoma, Hodgkin's or non-Hodgkin's disease



(1) findings on physical examination

(2) findings on appropriate imaging study

Criteria for hepatic involvement:

(1) palpable liver

(2) positive imaging findings


Findings on PET-CT Scan

Findings on CT Scan

diffuse FDG uptake


solitary mass
