150. Indeterminate FNAC in thyroid nodules – How certain do we want to be?

Abstract

Background: it is estimated that a palpable thyroid nodule, which has a prevalence of 5%, is a follicular neoplasm in 15-20% of cases. All patients with a solitary thyroid nodule should have fine-needle aspiration cytology (FNAC) as the initial screening test but, unlikely, up to 30% patients with nodular thyroid disease will receive a FNAC report diagnostic for follicular lesion, or suspicious. Thence, most patients with follicular lesions will require surgical management.
