Notes

About the McGill thyroid nodule score

• The McGill thyroid nodule score combines
  • demographics
  • patient history and risk factors
  • imaging findings
  • US-guided fine needle aspiration biopsy (FNAB) results

• The McGill thyroid nodule score can be used primarily if the FNAB results are indeterminate (15-48% of all biopsies)

• It has been shown that the McGill thyroid nodule score correlates the risk of malignancy

• It has also been shown that thyroid nodules with indeterminate FNAB results which were subsequently found to be malignant by postoperative histopathology have a higher median McGill thyroid nodule score (9) than nodules which were found to be benign (7)
