Features of post-radioiodine whole body scan in non-invasive Follicular Thyroid Neoplasm with papillary-like nuclear features (NIFTP)

ABSTRACT

carcinoma has been reclassified as non-invasive follicularthyroid neoplasm with papillary-like nuclear features (NIFTP)to emphasize the benign nature of this entity. In ourinstitution, we have assessed 455 patients treated withradioiodine ablation for differentiated thyroid carcinoma and20 of them were retrospectively found to fulfill the newNIFTP criteria. There was no evidence of metastasis on postradioiodine whole body scans for NIFTP cases and thesepatients were in remission subsequently. The benignfeatures of these patients’ whole body scans and goodclinical outcome following treatment further support NIFTPas a low risk thyroid neoplasm.
