What is the sonographic appearance of thyroiditis?

They most commonly appeared as solid hyperechoic nodules with ill-defined margins. However, the echogenicity was variable, and calcification and cystic-appearing regions were also noted. The vascularity of these nodules as assessed with color Doppler and power Doppler sonography also varied widely.

How is thyroiditis detected?

In healthy adults without iodine deficiency, a normal thyroid gland is approximately 4 to 4.8 x 1 to 1.8 x 0.8 to 1.6 cm in size, with a mean sonographic volume of 7 to 10 mL and weight of 10 to 20 grams [2-4].

Can subacute thyroiditis be seen on ultrasound?

Conclusions. Subacute thyroiditis is the most common cause of non-autoimmune thyroiditis [7]. In addition to the typical clinical signs, characteristic ultrasound findings of subacute thyroiditis include the presence of an ill-defined hypoechoic area with a nonhomogeneous pattern [8].

What is the most common cause of thyroiditis?

Thyroiditis is caused by an attack on the thyroid, causing inflammation and damage to the thyroid cells. Antibodies that attack the thyroid cause most types of thyroiditis. As such, thyroiditis is often an autoimmune disease, like juvenile (type 1) diabetes and rheumatoid arthritis.
