Thyroid nodules are ovoid or spherical lesions with different radiological and consistency characteristics from surrounding normal thyroid tissue. They are the most common disease of the thyroid, and their frequency increases with age. Iodine deficiency is the most common cause of the nodule formation. Etiology of thyroid nodules has a wide range from a simple benign nodular goiter to primer and secondary malignancies.
Etiology of thyroid nodules has a wide range from a simple benign nodular goiter to primer and secondary malignancies. The most important aspect of a nodule for a clinician is the elimination of cancer suspicion by evaluating the likelihood of cancer. The prominence of thyroid nodules starts at this point. Every thyroid nodule must be evaluated in terms of malignancy and absolutely must be followed at certain intervals. When a nodule is detected by physical examination or radiological examination, it is necessary for the patient to be questioned regarding their thyroid cancer risk factors such as family history of thyroid cancer, and radiation application story regarding the whole body; especially the head and neck region.
Alarming findings in a patient with thyroid nodule include having a thyroid cancer positive family story, head, and neck radiation receiving story, childhood thyroid nodules and permanent dysphonia, dysphagia, or dyspnea. Serum TSH measurement also should be evaluated in all patients with thyroid nodules detected. The TSH result is an important criterion for approaching the patient who has the nodule.
Thyroid USG is the key test for thyroid nodule evaluation. USG is an easily accessible, noninvasive and cost-effective test. With thyroid USG, we can obtain many data such as nodule size, cystic-solid characteristic, calcification characteristics, settlement, echogenicity, edge organization, halo existence, and blood circulation characteristics.
Thyroid scintigraphy should be performed if TSH is suppressed in patient. Certainly, thyroid fine needle aspiration biopsy (FNA) is the gold standard test for the discrimination of the nodule from benign. There are the different approaches and different guidelines about which patient has to undergo FNA. Today, we want to speak about these current guidelines.
