Thyroid nodules are usually not necessary for pathology.
In thyroid ultrasonography, the observation of thyroid nodules with clear boundaries, no calcification, no surrounding abnormal blood flow, and regular nodule morphology are considered to be benign, and pathology is generally not required in such cases. If the thyroid nodule shows signs of malignancy such as aspect ratio greater than 1, unclear nodule border, and abundant surrounding blood flow signal, pathological examination may be required.
The TI-RADS classification criteria are mostly used to grade and assess the benignity and malignancy of thyroid nodules.
Grade 1 is no nodule. The malignancy rate is 0%;
Grade 2 is a benign nodule with a 0% malignancy rate;
Grade 3 is a possibly benign nodule with a malignancy rate of less than 2%.
Within grade 4, there are 4A, 4B, and 4C, where. 4A is low suspicion of suspected malignancy with a malignancy rate of 2%-10%, 4B is moderate suspicion of malignancy with a malignancy rate of 10%-50%, and 4C is highly malignant. The malignancy rate is 50%-95%;
5 extremely highly suggestive of malignant nodules with a malignancy rate greater than 95%;
6 extremely biopsy-proven malignant nodules.
Clinical often based on ultrasound grading to guide the next diagnosis and treatment, thyroid nodules 1-2 malignant rate of 0%, no puncture biopsy indications, so not all thyroid nodules must do pathology.
Patients diagnosed with thyroid nodules should go to the hospital and ask the doctor to take into account the specific circumstances of the case to determine the need for pathology.
