Moderate echogenicity of thyroid nodules is the visualization of thyroid nodules under ultrasound, which is a very common clinical condition with a very high prevalence and a detection rate of about 60% with ultrasound. The descriptive terms for moderate echo ultrasound include hypoechoic, moderate echogenicity, and hyperechoic. Moderate echogenicity indicates close proximity to thyroid echogenicity and is usually suggestive of adenoma.
Thyroid nodules found on ultrasound should be taken seriously and further thyroid function tests and, if necessary, a puncture should be performed to clarify the nature of the nodule. If the results of thyroid function and puncture are not abnormal, the nodule can be temporarily observed and the thyroid ultrasound can be repeated every 6 months without special treatment for the time being.
If the thyroid nodule is enlarging or if there are uncomfortable symptoms, it needs to be removed surgically to avoid further enlargement or malignancy.
If the biopsy result is normal, medication should be given as soon as possible for abnormal thyroid function; if the puncture result is abnormal, surgery should be given as soon as possible. The incidence of thyroid nodules is high in clinical practice, as is the incidence of thyroid cancer, but the prognosis is generally better with early detection and treatment.
