Thyroid nodule category 4a with calcification suggests suspected malignancy, and surgery can be avoided if the puncture pathology is benign, or surgery is recommended if the puncture pathology is malignant.
The grading of thyroid nodules is generally divided into 0~6 grades, with the degree of malignancy increasing in order, in which category 4a suggests a low degree of suspected malignancy (malignancy is approximately between 2% and 10%). If accompanied by tiny calcifications, it suggests the possibility of malignancy and further fine needle aspiration biopsy is required to clarify the nature of the thyroid nodule.
If the cytologic examination is benign and the nodule is not large in size, there are no other symptoms, and it does not affect normal life, regular follow-up observation is required. If the nodule is determined to be malignant by cytology, or if there are clinical signs of malignancy such as tracheal or esophageal compression symptoms (e.g., dyspnea, dysphagia), rapid enlargement of the nodule, and enlargement of the surrounding lymph nodes, surgical treatment needs to be considered.
Thyroid nodule category 4a with calcification should be taken seriously, and it is recommended to follow the doctor’s advice and treatment under the doctor’s guidance.
