We report a case of splenic marginal zone B-cell lymphoma discovered in a 73-year-old man with cold agglutinin disease. PET/CT revealed splenomegaly with focally intense uptake of F-FDG and diffusely increased bone marrow uptake, which was considered to be secondary to hemolytic anemia. Splenectomy was performed. The histopathology of the spleen showed splenic marginal zone B-cell lymphoma with partial splenic infarction, which correlated with the area of focal intense FDG uptake. Depending on the time since onset, splenic infarctions can present as focal FDG accumulation.
