Warm nodules

Introduction "Warm nodules": Radioactive development of nodules is the same as radioactive development of surrounding thyroid tissue. This nodule is more common in benign thyroid tumors.

Cause

What is the cause of the warm nodules?

The cause of thyroid tumors is not clear. At present, there are two reasons for the etiology of differentiated thyroid cancer (including papillary and follicular carcinoma): one is radiation, and the other is endemic goiter.

How should the temperature nodules be diagnosed?

Radionuclide check

This test should be a routine diagnostic tool for the thyroid gland, with radionuclides: 131I and 99mTc. X-ray and CT, magnetic resonance imaging (MRI) examination.

Differential diagnosis

What are the symptoms of warm nodules that are easily confused?

Differential diagnosis of warm nodules:

1. Thermal nodules: "hot nodules": radioactive development of nodules is higher than surrounding thyroid tissue. Such nodules are generally more functional nodules, and patients often have hyperthyroidism. Hot nodules are generally not cancerous.

2. "Cool nodule": Radioactive development of nodules is lower than development of surrounding thyroid tissue. This nodule is also common in benign tumors of the thyroid gland and also in thyroid malignant tumors.

3. "Cold nodule": No nodules are developed by the nodules. This nodule is found in a variety of diseases, from thyroid cancer to various benign lesions (such as cysts, hemorrhage, and fibrous necrosis). However, if the cold nodules are large, the boundary with the surrounding thyroid tissue is unclear, and it is a single nodule, it is their significance to pay attention to the possibility of having thyroid cancer.

Radionuclide examination: This examination should be a routine diagnostic tool for the thyroid gland: 131I and 99mTc. X-ray and CT, magnetic resonance imaging (MRI) examination.
