Thyroid nodule is detected in 4–7% of the general population and 15–25% of nodules are cystic [1]. TSH suppression therapy by administering T4 is not effective. Before the 1980s, cystic nodules were treated surgically if aspiration and drainage of fluid could not reduce their volumes. However, in the 1990s, an increasing number of PEIT treatments were reported. Ethanol directly makes tissue necrotic by coagulation of proteins and secondarily destroys tissue by forming thrombi in microscopic blood vessels.
