A 48-year-old male patient post total thyroidectomy with PTC recurrence. a Transverse greyscale ultrasound of the neck demonstrates a left thyroid bed heterogeneous, predominantly hypoechoic irregular lesion with calcifications (white arrow). b A spot image of iodine 123 total body scan of the neck demonstrate a focus of abnormal radiotracer uptake at the left thyroid bed (Black arrows) between the annotated markers. c Enhanced axial CT scan of the neck demonstrates an enhancing large left thyroid bed mass (white arrow) with no calcifications. The lesion exerts a mass effect on the oesophagus (black arrow) and is inseparable from the trachea
