Percutaneous ethanol injection into thyroid cysts

Thyroid nodule which is one of the most frequently encountered thyroid diseases is characterized by growth of abnormal tissues into the thyroid gland. Its incidence varies among populations, and geographic regions. Nowadays, thanks to more frequent use of imaging modalities, thyroid nodules have been detected in individuals with complaints, and many asymptomatic patients as well. The incidence of thyroid nodules in our country is estimated to be 33.3 per-cent.[1] Thyroid nodules have been classified as solid, and cystic based on the anatomic structure of the lesion. While majority of the nodules demonstrates benign characteristics, malignant nodules have been also reported in various fre-quencies. Though malignancy is more frequently encoun-tered in solid lesions, many studies have indicated that cys-tic lesions can be malignant as well, and clinical findings, and demographic data of the patients might fail to discrim-inate between benign, and malign lesions.[2] Öze
