Representative case from the group with daily maintenance dose of prednisone of ≤ 10 mg (patient no. 3). Pretreatment FDG PET/CT (a 3D maximum intensity projection; b, c, d, e fused PET/CT) demonstrate multiple organ diseases involving lymph nodes (thoracic and abdominal), the lung (c, arrows), bones (e arrowhead), heart (d, e arrows), liver, and spleen. Reconstructed short axis images of the left ventricle (h perfusion images on the top and FDG images on the bottom) show increased metabolic activity in the inferolateral wall with corresponding mildly reduced perfusion (arrowheads), suggestive of active inflammation. The max SUV, metabolic volume, and total lesion glycolysis of all involved organ system and the heart are 7.5 (liver), 1860.9 ml, and 6866.9 g, and 5.7, 84.1 ml, and 294.4 g, respectively. Follow-up PET/CTs performed at 3 months (f) and 9 months (g) since the initial study show complete metabolic resolution. The patient initially received 40 mg of corticosteroid daily, which reduced to 0 mg at 6 months
