38-year-old lady presented with fever of four months duration associated with anorexia, weight loss and myalgia. Maximum intensity projection fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) whole body image reveals multiple areas of increased FDG uptake throughout the body. Coronal PET/computed tomography (CT) image (b) localizes the patchy uptake to multiple skeletal muscles (arrow) (maximum standardized uptake value [SUVmax] = 2.4). (d) Diffusely increased FDG uptake in the enlarged spleen (SUVmax = 3.5). Diagnosis of inflammatory pathology involving muscles was made on PET/CT. Although creatine phosphokinase levels were normal but electromyography showed myopathic pattern and muscle biopsy revealed dermatomyositis
