The noninvasive encapsulated follicular variant of papillary carcinoma (nEFVPTC) has recently been reclassified to “noninvasive follicular thyroid neoplasm with papillary‐like nuclear features (NIFTP),” removing this entity from the malignant category. This re‐categorization has had major implications for clinical management. NIFTP has overlapping cytohistologic features with papillary thyroid carcinoma (PTC) and with follicular adenomas (FA), but sonographic data comparing NIFTP to PTC and FA is lacking. Our study examines the sonographic features of NIFTP as compared with PTC and FA.
