Figure 3: Positron emission tomography-computed tomography fusion images. Fluorodeoxyglucose avid recurrence in the thyroid bed with maximum standardized uptake value of 11.0 ml/g. A focal lesion within the right sternocleidomastoid can be seen with maximum standardized uptake value of 9.42 ml/g. Multiple fluorodeoxyglucose avid nodules in both lung fields (maximum standardized uptake value = 8.77 ml/g)
