Diagnostic accuracy of Thyroid Imaging Reporting and Data System in the prediction of malignancy in nodules with atypia and follicular lesion of undetermined significance cytologies

Abstract

TIRADS seems to be useful in predicting malignancy and planning further management in the AUS subcategory, but not quite so in the FLUS subcategory.

Web‐based thyroid imaging reporting and data system: Malignancy risk of atypia of undetermined significance or follicular lesion of undetermined significance thyroid nodules calculated by a combination of ultrasonography features and biopsy results

“…gap.kr/thyroidnodule_b3.php). 30 In our web-based scoring system, the AUCs for the subcategories of cytologic atypia and architectural atypia were 0.860 and 0.658, respectively, which are higher than those reported in the previous study. The American Thyroid Association management guidelines for thyroid nodules, 7 Korean Society of Thyroid Radiology consensus statement and recommendations, 6 and French guidelines 26 on the stratified risk of malignancy of thyroid FI GU RE 2 Performance of 2 prediction models.…”

“…As previous literature reported that the differentiation between follicular adenoma and carcinoma using ultrasound is limited, 30,37,38 we speculate that it contributed to the relatively low AUC in architectural atypia. First, the study population was not free from selection bias, and it could not be determined whether the patients were representative of the general population.…”

“…To improve the accuracy of this system, we used detailed information from multiple features of the ultrasound images and pathologic results, with the inclusion of data from two different centers. 10,[28][29][30] The malignancy risk stratification of AUS/FLUS thyroid nodules using a combination of ultrasound features and cytologic results has 2 important benefits. Furthermore, this system can calculate the malignancy risk according to a scoring system (for scores of 0-12, the risk of malignancy is 11.2%-98.1%) available on a website (www.…”

Non-functioning parathyroid cystic tumour: malignant or not? Report of a case

“…The cystic shape and the intrathyroidal location of the focal lesion led us to perform a FNAB that resulted non-conclusive. On the other hand, we think that the lack of knowledge directing towards a parathyroid origin leads to a FNAB for evaluating this neck mass (11,(30)(31)(32). In the absence of hypercalcemia, the pre-operative parathyroid origin of the neck lump cannot be established.…”
