Achilles Tendonitis Detected by FDG-PET

Abstract
Increased metabolic activity in the region of the Achilles tendon is occasionally noted when the lower extremities are studied with PET scans. Although tendonitis has been a possible explanation for the uptake, corroborative evidence from other imaging modalities is usually absent. We report a case of abnormally increased FDG uptake in the Achilles tendon correlated with a diagnosis of tendonitis and MRI imaging abnormalities.
