Overview
CT scan
CT scan is not a good choice for cervical lymph node metastases evaluation because its sensitivity is low (30-40%), but as an alternative imaging modalitiy, it may be useful in the assessment of tumors with the following features:
- Large tumors
- Rapidly growing tumors
- Retrosternal tumors
- Invasive tumors
- To assess the involvement of extrathyroidal tissues

Thyroid nodule rupture:
Sonography and/or computed tomography (CT) could help diagnose this complication, which is visualized as the breakdown of the thyroid capsule and the formation of a new mass located between intra- and extra-thyroidal lesions at the RF site
