Thyroid Gland

[thumper9095]

I have hypothyroidism. Found a very calcified nodule in left side measuring 6x6x5cm. Followup ultrasound shows same nodule measuring 6x5x5cm. But the conclusion also says: "Diffuse heterogeneity of the gland" and "Stable peripherally calcified nodule in the left lobe. What does all of this mean? My TSH level is 1.? (something) right now.

Heterogeneity means the the texture of the thyroid gland isn't uniform and smooth as seen with a healthy thyroid gland. This texture is spread over the thyroid gland (diffuse). A diffusely heterogeneous thyroid is commonly seen with an autoimmune disease called Hashimoto's thyroiditis.

Thyroid calcification is a solid or semi-solid lump within the thyroid gland. Reasons for thyroid calcification include iodine deficiency and Hashimoto's thyroiditis.

Excerpt from the study "Peripheral calcification in thyroid nodules: ultrasonographic features and prediction of malignancy." J Ultrasound Med. 2007 Oct;26(10):1349-55; quiz 1356-7.

"RESULTS:
Twelve (18.5%) of 65 thyroid nodules with peripheral calcification were malignant, and 53 (81.5%) were benign. Patient demographics (age and sex) and ultrasonographic features of the nodules (size, shape, internal echogenicity, halo sign, and type and extent of calcification) did not show any significant differences between benign and malignant groups.

CONCLUSIONS:
The relatively high prevalence of malignancy and no reliable criterion for malignancy in thyroid nodules with peripheral calcification indicate that fine-needle aspiration or careful ultrasonographic follow-up may be warranted in these cases."
