Overview

CT scan may be helpful in the diagnosis of papillary thyroid cancer.

CT is best at staging lymph node involvement (see thyroid cancer staging). Involved lymph nodes tend to have 1:

cystic components: ~35%
thick nodular walls: ~40%
septa: ~60%
purely cystic nodes are uncommon and more frequent in young patients
calcification may be seen occasionally
the so-called lateral aberrant thyroid is actually a lymph node metastasis from papillary thyroid carcinoma
