Cystic solid nodule in the right lobe of the thyroid gland is one of the common thyroid nodules. It is usually a benign lesion and can be reviewed regularly if there are no obvious symptoms, but if compression symptoms appear, surgery needs to be considered under the guidance of a doctor. With the popularization of medical checkups and more extensive screening with thyroid ultrasound, the detection rate of thyroid nodules has increased. Most thyroid nodules are benign lesions that do not affect the body. They do not require medication, but only regular follow-up. If the nodules are found to have increased in size and changed in nature during follow-up visits, they may need to be removed surgically, and there is a possibility of post-operative hypothyroidism, which may require medication. When thyroid nodules are detected, it is recommended to seek prompt medical attention.
