Metastases to the thyroid are an uncommon cause of thyroid malignancy.
Epidemiology
Metastases to the thyroid represent 1.4-3% of all malignancies . In autopsy series, the incidence is ~10% (range 2-24%) .
Pathology
The most common sites of primary malignancy include (note these will vary by region) :
- kidney
- renal cell carcinoma (considered most common)
- lung
- head and neck
- breast
- gastrointestinal tract
- skin
- neuroendocrine tumor
- cholangiocarcinoma (rare)
Radiographic features
Ultrasound
Metastases to the thyroid most commonly have the following features :
- hypoechoic lesion with poorly circumscribed margins (80%)
- no calcifications
- concurrent cervical lymphadenopathy (80%)
