Abstract
White adipose tissue (WAT) generally has negligible glucose utilization and thus, shows no or insignificant Fluorine-18 fluoro D-glucose (FDG) uptake. However, corticosteroids can cause altered biodistribution of FDG with increased uptake in WAT. We hereby describe a case of immune complex-mediated glomerulonephritis showing diffusely increased FDG uptake in WAT secondary to high-dose corticosteroid therapy.
