Study about Sonographic Features of Thyroid Nodules to Differentiation between Benign and Malignant Among Patients from El-Beida City

British Thyroid Association (BTA) recently produced Ultrasonography (US) classification (U1–U5) of thyroid nodules to facilitate the decision-making process regarding the need to perform fine-needle aspiration cytology (FNAS) in suspicious/unequivocal cases. This study was aimed to evaluate whether a relation between classify thyroid FNAS cytology, ultrasound feature diagnoses and compare with BTA-U classification. All the FNAS of thyroid lesions came during November 2017 to November 2018 were classified depended one echogenicity and size vascularity and type of calcification by assed the indication of FNAS and final cytology results. During the study period, total of 165 (89.7% females and 10.3% males) was enrolled in this study. Thyroid FNAS were reported to benign lesion, malignant, inflammatory, indeterminate and non-diagnostic were reported in (76.5 and 87.8%), (5.9 and 2.03%), (5.9 and 6.8%), (0 and 2.03%) and (11.8 and 1.35%) in cases of (male and female) respectively. Benign cases were found 757 (95.2%) out of total 795. This category includes hypo echogenic, hyper echogenic, iso echogenic, highly vascular nodules, calcification, well defined nodular surface, lymph adenopathy, mixed solid& cystic and halo sign depending to sonographic description comparison with BTAU. This study concluded that Use of BTA for thyroid FNAC reporting helps to highlight increased malignancy risk associated with US and FANS malignant categories as well as provide more details related to cytology of thyroid lesions.
