FDG uptake in a rheumatoid nodule with imaging appearance similar to a malignant soft tissue tumor.

摘要

Partial-body F-18 FDG PET/CT was performed in a 40-year-old woman with a soft tissue tumor at the left elbow. She had rheumatoid arthritis for several years. PET/CT showed moderate FDG uptake (SUV max. 4.2) in the known soft tissue lesion. The tumor was resected and histology revealed rheumatoid granulomas with bursitis.
