Welcome to HealthcareMagic Forum,
Thyroid gland can be compared to a honeycomb where in the spaces are filled with some semisolid material called colloid. In some thyroid conditions there is deposits of a mineral called calcium (as in bone) over the soft tissues in the thyroid forming a dense nodule called calcification. This can sometimes lead to the thyroid cancer
. In this case there are some small opacifications which can be calcium deposits in the thyroid gland.
