Ultrasonography‐guided fine‐needle aspiration of thyroid incidentaloma: correlation with pathological findings

Abstract

The rate of malignancy in incidentally detected impalpable thyroid nodules was 12% in retrospective analysis of our patients. In this subgroup, 69% (25/36) of patients had either extrathyroidal extension or regional node involvement and 39% had multifocal tumours at surgery. This suggests that the small size alone does not guarantee low risk in incidentally found thyroid cancers. USGFNA is a useful diagnostic method in these patients.
