A 32-year-old woman is found to have a 1.8 cm thyroid nodule on ultrasound. FNAC is Bethesda Category II (benign). According to the 2015 ATA guidelines, what is the recommended follow-up?
- A Repeat FNAC in 6 months
- B Repeat ultrasound in 12 to 24 months ✓
- C Perform molecular testing for BRAF mutation
- D No further follow-up needed
Correct answer: B. Repeat ultrasound in 12 to 24 months
Explanation
For benign thyroid nodules, the 2015 ATA guidelines recommend repeat ultrasound surveillance in 12 to 24 months to assess for growth. Routine repeat FNAC is not indicated for cytologically benign nodules unless significant growth occurs. Molecular testing is reserved for indeterminate cytology (Bethesda III or IV). Complete cessation of follow-up is not recommended as some benign nodules grow over time.
