Abstract: Objective To summarize the extra-bone joint characteristics of 18F-FDG PET/CT images in patients with adult-onset Still's disease. Methods Twelve patients with adult-onset Still's disease as confirmed by clinical and laboratory tests were enrolled in this study. The characteristics of 18F-FDG PET/CT images were retrospectively analyzed. Results Among the 12 patients, no patients were found with solid malignant tumors. Various degrees of high uptake were found in liver, spleen, bone marrow or lymph node. The hepatic SUV was 2.74 ± 0.89, the spleen SUV was 3.68 ± 1.24, and the SUV of thoracic spine was 4.36 ± 1.35. For the lumbar vertebral, the value of SUV was 4.26 ± 1.25. Lymph node high uptakes were found in 8 patients at different sites , including retroperitoneal , pelvic cavity and pelvic wall , inguinal bilateral neck , hepatic portal , axillary lymph nodes. The value of SUV was 3.76 ± 1.41. Conclusions 18F-FDG of AOSD has certain characteristics, such as diffusely uptake of liver, spleen, bone marrow, or lymph node, with or without pleural effusion.
