AfHNS guidelines for evaluation of a thyroid nodule / mass


  • After addressing possible thyrotoxicosis, U/S  may assist to differentiate a single hypervascular (potentially hyperfunctional) nodule vs. diffusely hypervascular goiter (Graves disease)
  • Note that FNAC of a hypervascular (hyperfunctional) nodule has reduced sensitivity and specificity
  • U/S can also be used to risk-stratify using the Thyroid Imaging Reporting and Data System (TI-RADS)
  • Indications for FNAC based on clinical and sonographic features
