A symmetric inverted "V" pattern of high uptake in the floor of the mouth is a consistent normal finding on F-18 FDG PET. There is no general agreement on the nature of this highly FDG-avid structure. Mylohyoid muscle, insertion site of the genioglossus muscle, other intrinsic tongue muscles, and the sublingual gland have been suggested. I-123 SPECT and F-18 FDG PET scans were performed on the same day in a patient with papillary thyroid carcinoma. Both the I-123 SPECT and F-18 FDG PET showed the same inverted "V" pattern in the floor of the mouth, corresponding to the sublingual gland typically seen on magnetic resonance imaging.
