A STUDY COMPARING ULTRASONOGRAPHY, FINE NEEDLE ASPIRATION CYTOLOGY FEATURES WITH HISTOPATHOLOGY IN DIAGNOSIS OF THYROID SWELLINGS.

Background High resolution ultrasonography (USG) is the rst-line investigation in evaluation of euthyroid nodules. Thyroid imaging reporting and data system (TIRADS) is an USG-based risk stratication system for classifying thyroid nodules. Subjects with high-risk category of TIRADS undergo ne needle aspiration cytology (FNAC) and FNAC ndings are reported according to Bethesda classication. Bethesda categories are used for determining risk of malignancy. The aim of this study is to compare the accuracy in diagnosing Thyroid swellings by USG with TIRADS score ,FNAC with BETHESDA score and the Histopathological diagnosis in patients who underwent surgery. Materials and methodsIt is Retrospective Observational study done in Basaveshwara Teaching and General Hospital with 54 cases .All patients USG FNAC done data collected and compared with HPE report Results Study observes that, maximum number of patients 19 (35.2%) were belongs to the age group of 21—30 year, followed by 14 (25.9%) of patients were seen in the age group of 31—40 years. The sex ratio male to female was 1:8.In the study majority of patients 29 (53.7%) were seen multi nodular goiter lesions, followed by 11 (20.4%) were solitary thyroid nodule lesions .colloid goiter were 14.8%, hashimotos thyroiditis patients were 11%.Study observed; female patients were predominant 48 (88.9%) and female patients were 6 (11.1%). Out of 11 solitary thyroid nodules 9 (81.8%) were seen follicular adenoma and 2 (18.1%) were seen follicular carcinoma. In the present study out of 54 sample thyroid lesions 2 (3.7%) were seen malignant. The study prevalence of thyroid carcinoma was 3.7% .The Accuracy sensitivity Specicity of usg was91.48% ,67.92%,93.32%.The Accuracy sensitivity Specicity of FNAC was 92.22%,82.52%,94.11%. Conclusion USG followed by FNAC increases the accuracy to diagnose various thyroid swellings so by which unnecessary thyroid gland surgery and hence complications can be avoided. However the most accurate and conrmatory diagnosis is given by histopathology
