Figure 4: Left column noncontrast CT and right fused PET/CT transaxial images. Noncontrast CT scan revealed absent normal thyroid gland, large 3.6 × 2.3 × 6.2 cm well defined lobulated hypodense infrahyoid cystic lesion with hyperdense peripheral wall and midline thin multiple septae reaching to the sternal notch (thoracic inlet). 18F-FDG regional neck PET/CT revealed no definite FDG uptake in the TGDC or elsewhere in the neck to suggest malignancy
