Rare Occurrence of Scapulothoracic and Ischiogluteal Bursitis Signifying Poorly Controlled Rheumatoid Arthritis

Abstract

Abstract A 74-year-old man with poorly controlled seropositive rheumatoid arthritis was referred for 18F-FDG PET/CT for follow-up of lung cancer, which demonstrated intense FDG activity in atlantoaxial, sternoclavicular, glenohumeral, and hip joints consistent with active rheumatoid arthritis. There was also unexpected intense uptake at scapulothoracic, ischiogluteal, and trochanteric bursae signifying active bursitis.
