Metastasen in der Schilddrüse
Squamous cell
carcinoma of the uterine cervix metastasising to the thyroid gland: a case report. Consecutive axial views of the contrast enhanced computed tomography of the neck showing multiple low-density thyroid nodules (yellow arrows), a mixed density mass lesion in the lower pole of the left thyroid lobe (green arrow) and multiple deep cervical lymph nodes (lower jugular and paratracheal) (red arrows)

carcinoma metastasis in thyroid gland mimicking a benign goitre. Axial contrast CT scan image of right thyroid mass.
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%)
