Clinical presentation Presentation is usually with a solitary palpable thyroid mass. Papillary carcinoma has a tendency to metastasise early to local lymph nodes, with 50% (39-90% 2 ) of patients having nodal involvement at presentation 1 (c.f. 10% for follicular thyroid cancer). These metastases are usually to the ipsilateral jugular chain (87.8%) and are usually confined to the mid and lower lymph node levels, level III and IV (73.2%) 1. In approximately 20% of patients lymph node metastases are the first presentation, with 50% of children and 20% of adults a palpable cervical lymph node palpable at the time of diagnosis 4. Distal haematogeneous dissemination is less common than with follicular cancer, with only in 5-10% of patients at presentation. CT 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 % • septae: ~ 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 .
