Figure 1.
A 50-year-old female patient with diffuse PTL.
Transverse sonogram shows the enlarged thyroid with decreased heterogeneous internal echoes (arrows).
Figure 2.
A 71-year-old female patient with diffuse PTL.
The longitudinal sonogram of left lobe shows the marked hypoechogenecity with posterior acoustic enhancement (arrows).
Figure 3.
A 55-year-old male patient with diffuse PTL.
The transverse sonogram shows the presence of macrocalcification (arrows).

Sonographic appearance of diffuse PTL.
Figure 4.
A 67-year-old male patient with non-diffuse PTL.
(A)The longitudinal sonogram shows that PTL was limited to the right thyroid lobe (arrows). (B) The longitudinal sonogram shows a heterogeneous echotexture of the left thyroid lobe (arrows).
Figure 5.
A 78-year-old female patient with non-diffuse PTL.
The transverse sonogram shows the extremely hypoechoic lesions (arrows) with posterior acoustic enhancement (arrow heads).
Figure 6.
A 56-year-old female patient with non-diffuse PTL.
The transverse sonogram shows the increased chaotic vascularity (arrows). (Tr: Trachea)
Figure 7.
A 78-year-old female patient with non-diffuse PTL.
The transverse sonogram shows the presence of a hyperechoic portion (short arrows) and microcalcification (long arrow) within an extremely hypoechoic PTL lesion.

A 65-year-old female patient with non-diffuse PTL.
The longitudinal sonogram shows the honeycomb appearance in a PTL lesion (arrows). (M: mass)
