Clinical history: goiter

The thyroid isthmus is unremarkable measuring 4.3-mm AP.

The right lobe is moderately enlarged measuring 5.1×1.7×2.9-cm. There is a 3-mm hypoechoic nodule in the lower pole of the right lobe.

Can you have a thyroid goiter without having a thyroid disorder such as hashimotos, graves.?

Heterogeneous echogenicity is commonly present during or after inflammation.
The volume of your thyroid is approximately
left lobe 12.3 ml
Right lobe 7.5 ml
total is 19.8
typically the volume is around 7.5 with upper limit 18 ml

If you know you're getting plenty of iodine, and don't eat the foods that can cause a goiter then would the goiter most likely be caused by a thyroid disorder such as graves or hashimotos? What could be any other causes for a goiter, and nodules.

Too much iodine in the diet
exposure to radioactive iodine fallout
inability to absorb iodine
PCOS
type I or II diabetes
Personal care product
birth control pills
weight loss supplements!
