Both lobes of the thyroid and isthmus are bulky in size and appear heterogeneously hypoechoic in echotexture with a marked diffuse increase in vascularity (thyroid inferno) on colour flow Doppler interrogation. The peak systolic velocity in the inferior thyroid artery is approximately 100-120 cm/sec.

A well-defined round solid iso to a hyperechoic lesion of size ~18.5 × 14.5 mm at the upper pole of the right lobe of the thyroid with no evidence of macro or microcalcification within it, likely adenomatous nodule (TI-RADS3 lesion).
