Thyroid gland with normal morphology and uneven echogenicity is a manifestation of ultrasonography, which may be caused by iodine abnormality, hyperthyroidism, thyroiditis, etc. It is recommended to consult relevant professionals for symptomatic treatment. 1. Iodine abnormality: iodine is required for thyroid hormone synthesis by the thyroid gland, and iodine deficiency may lead to endocrine disorders; high iodine may induce autoimmune thyroiditis, both of which may result in a non-uniformity of thyroid morphology and echogenicity. 2. Hyperthyroidism: In patients with hyperthyroidism, there will be abundant blood flow to the thyroid gland, and the thyroid gland may exhibit a non-uniform morphology and echogenicity. 3. Thyroiditis: These include subacute thyroiditis and Hashimoto’s thyroiditis, both of which may present with a hyperechoic thyroid. For patients with thyroid dysmorphic echogenicity, it is recommended to identify the cause and treat it promptly under professional guidance.
