Intranodular hyperechogenic figures - Table 7. Granulation around surgical thread

doi: 10.24390/thyrosite.2018.ihf.07.1

This hypoechogenic figure is usually irregularly shaped, contains ragged echonormal tissue which presents hyperechogenic granules. The latter might be as small as non-specific granules or larger than a punctate echogenic focus (microcalcification). A granulation is always avascular and very hard on palpation. This figure occurs in previously operated patients.

Granulation around surgical thread (cytological diagnosis) - case 1423

There is a relatively large echonormal tissue in the central part of the hypoechogenic mass. Note the acoustic shadowing. The lesion is avascular.
   

Granulation around surgical thread (cytological diagnosis) - case 1475

There are two granulations both in the left, horizontal and in the right, longitudinal images (arrows). The shape of the masses is irregular. The granulations are hypoechogenic and have one or more echonormal foci.
   

Granulation around surgical thread (cytological diagnosis) - case 981
The granulation pointed with calipers is located within the sternocleidomastoid muscle.
   

Granulation around surgical thread (histological diagnosis) - case 1386

This is a typical presentation of a granulation around surgical thread: a hypoechogenic, irregularly shaped, avascular mass having several echonormal areas corresponding to a ragged tissue.

   

Granulation around surgical thread (cytological diagnosis)
There are multiple hyperechogenic foci within the hypoechogenic mass.
   

Granulation around surgical thread (histological diagnosis) - case 411

This granulation has dorsal acoustic shadowing and contains bright, punctate echogenic focus-like granules within an echonormal mass.
