Tc-99m pertechnetate thyroid scan demonstrates inhomogeneous, generally increased uptake throughout the gland without clearly distinguishable cold nodules.
The uptake in the structure going upwards from right thyroid lobe was not removed by swallowing a significant amount of water and thus most likely represents increased uptake in a pyramidal lobe (embryonic remnant of thyroglossal duct), an additional finding suggesting general high degree of uptake.
