Table 1 Pathognomonic patterns

In the upcoming cases we demonstrate several examples of nonparallel orientation.

Papillary carcinoma (histology) - case conp020

Transverse scan
Longitudinal scan

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.

 

Papillary carcinoma (histology) - case conp036

Transverse scan
Longitudinal scan

The nodule presents both taller-than-wide and taller-than-long shape.

 
 

Papillary carcinoma (histology) - case conp030

Transverse scan
Longitudinal scan

The lesion present taller-than-long shape while does not taller-than-wide sign.

 

Papillary carcinoma (histology) - case conp033

Transverse scan
Longitudinal scan

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.

 

Papillary carcinoma (histology) - case conp043

Transverse scan
Longitudinal scan

The small lesion in the dorsal part of the lobe presents both taller-than-wide and taller-than-long shape.
