(18)F-FDG PET/CT imaging in systemic lupus erythematosus related autoimmune haemolytic anaemia and lymphadenopathy.

A symmetrically increased (18)F-FDG uptake in small lymph nodes with multiple serous cavity effusion helped the differential diagnosis between SLE related AIHA and lymphoma. In addition, PET/CT can visualize not only the degree of disease activity or the "burden of inflammation" but also the distribution of the disease in the entire body.
