An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [33]
If ultrasound results are equivocal or unclear, or if the thyroid nodule is small (typically less than 1 cm), the nodule can be monitored over time with serial ultrasounds. [10] Ultrasound has a sensitivity of 64-77% and a specificity of 82-90% for the detection of thyroid cancer. [10]
Treatment of a thyroid nodule depends on many things including size of the nodule, age of the patient, the type of thyroid cancer, and whether or not it has spread to other tissues in the body. If the nodule is benign, patients may receive thyroxine therapy to suppress thyroid-stimulating hormone and should be reevaluated in six months. [2]
An incidentally discovered colloid nodule with calcification, shown on CT scan of a 58-year-old female patient. a Non-enhanced axial CT scan of the neck demonstrates a coarse calcification at the left thyroid inferior pole. b Sagittal grey scale ultrasound of the thyroid demonstrates a heterogeneous nodule with a predominant cystic component.
Colloid nodules may be initially identified as an unspecified kind of thyroid nodule. Follow-up examinations typically include an ultrasound if it is unclear whether or not there really is a nodule present. Once the presence of a nodule has been confirmed, the determination of the kind of thyroid nodule is done by fine needle aspiration biopsy. [7]
Papillary thyroid carcinoma is usually discovered on routine examination as an asymptomatic thyroid nodule that appears as a neck mass. In some instances, the mass may have produced local symptoms. This mass is normally referred to a fine needle aspiration biopsy (FNA) for investigation. FNA accuracy is very high and it is a process widely used ...
A cold nodule is a thyroid nodule that does not produce thyroid hormone. [1] On a radioactive iodine uptake test a cold nodule takes up less radioactive material than the surrounding thyroid tissue. [1] A cold nodule may be malignant or benign. [1] On scintigraphy cold nodules do not show but are easily shown on ultrasound. [2]
Regular monitoring mainly consists of watching for changes in nodule size and symptoms, and repeat ultrasonography or needle aspiration biopsy if the nodule grows. [8] For patients with benign thyroid adenomata, thyroid lobectomy and isthmusectomy is a sufficient surgical treatment.
