A seventy years old female patient, diagnosed with follicular differentiated cancer thyroid. Underwent total thyroidectomy, followed by 100 mCi RAI-131 ablation. Follow up iodine whole body scan was negative,yet, elevated thyroglobulin level (= 15.5 mg/dl). Ultrasound of the neck showed operative bed ill-defined soft structure of indeterminate sonographic nature, PET/CT demonstrates operative bed soft tissue lesion with increased activity (SUV ~ 4) denoting operative bed local recurrence. Axial PET only (a), CT (b) Axial & Coronal fused PETCT images (c, d) show operative bed soft tissue lesion
