A case of Tietze's syndrome visualized on PET/CT-FDG.

We report an interesting image of a 49-year-old woman revealed with Tietze's syndrome (TS) by ¹⁸F-FDG PET/CT. She presented with right upper sternum pain with a hard and fixed palpable mass. Chest radiograph and CT-Scanner revealed no abnormalities. PET/CT-FDG showed a hypermetabolic activity around right sternoclavicular joint, which was the correct symptomatic lesion. Hence, FDG PET/CT may be useful for diagnosing TS and to accurately detect the symptomatic lesion.
