Non-Toxic Multinodular Goiter: From Etiopathogenesis to Treatment.

Goiter term is generally used for defining the enlargement of thyroid gland. Thyroid nodules are very common and some of these nodules may harbor malignancy. Multinodular goiter (MNG) disease without thyroid dysfunction is defined as non-toxic MNG. There are many factors in etiology for development of MNG. They can be classified as iodine dependent and non-iodine dependent factors basically. Beyond this basic classification, the effect of many environmental and acquired factors is also effective on the development of goiter. Many methods have described for diagnosis and treatment for non-toxic MNG. Biochemical tests, imagining methods, invasive and non-invasive methods have been used for diagnosis for many years. Each method has advantages and disadvantages, separately. Although the best method for diagnosis is still debatable, distinguishing malignant nodules from benign nodules is the first and most important step for MNG. Biochemical tests such as serum thyroid stimulating hormone (TSH) measurement, thyroid hormone measurement; and thyroid ultrasonography are used for diagnosis of MNG, traditionally. Nowadays, there are some new techniques were developed like ultrasound-elastography. Furthermore, thyroid scintigraphy may be used if there is abnormal TSH measurement. Fine-needle aspiration biopsy and some cross-sectional imaging methods (computed tomography, magnetic resonance imaging, and positron emission tomography) could be used, too. After a certain diagnosis is made, treatment options should be evaluated. Many treatment methods have been used for goiter from ancient times upon today. From non-invasive methods such as medical follow-up to invasive methods such as lobectomy or thyroidectomy are options for treatment. Patients with compression symptoms due to an enlarged thyroid gland are usually candidates for surgery. In this study, it is aimed to determine the most appropriate treatment for the patient by discussing the advantages and disadvantages of all these methods. The present review discusses definition of goiter term, etiology, epidemiology, pathogenesis, diagnostic methods, and treatment methods for nontoxic MNG. ©Copyright 2022 by The Medical Bulletin of Sisli Etfal Hospital - Available online at www.sislietfaltip.org.
