The nodule presents the taller-than-wide shape on transverse scan because the depth (antero-posterior diameter) clearly exceeds the width (latero-medial diameter) of the nodule. On the hand, taller-than-long shape is not present on longitudinal scan because the depth (antero-posterior diameter) is lower than the length (the diameter measured from the upper to the lower pole of the nodule). The depth is signed with white, the width is with red while the length is with yellow arrows.

The nodule is just at dorsal surface of the lobe. Between the two arrows there is a part of the border in which extrathyroidal spread is conceivable (yellow arrows). The nodule shows taller-than-wide shape.
