Hi Linh,

There are rules for this in the Tirads system,

Tirads has a couple of supporting documents which are fabulous to read as they explain all of these small issues and provide guidance,

I must get around to recording my thyroid lecture soon as I think it will be helpful.

The Tirads rules say that if you cannot see the internal architecture of a lesion due to complete or near complete egg shell calcification you do the following :

Assume it is solid (2 points)
Assume it is isoechoic ( 1 point)
Allocate peripheral calcification points (2 points)

So they get 5 points.

I agree with you that these are often benign and often there is evidence they have been there for ages unchanged,

But they are the RULES !!!!
