A prospective study of ultrasonographic and FNAC correlation of thyroid pathology

Introduction: Fine Needle Aspiration Cytology (FNAC) of the thyroid gland is a well established first-line diagnostic test for the evaluation of diffuse thyroid lesions as well as thyroid nodules. It is found to be the most useful line of investigation than other investigations like ultrasonography (USG), thyroid function test (TFT), thyroid scan and serologic studies. Material and methods: Prospective study of minimum 100 cases was carried out with thyroid lesions that underwent USG thyroid and FNAC during the period of 1st January, 2014 to 31st December, 2014 were included. Results: Radiologically, 70% cases were diagnosed as benign thyroid lesion, 7% as malignant and 23% were diagnosed as indeterminate. While on FNAC, 83% were benign thyroid lesions and 6% were malignant, 8% were follicular neoplasm and 3% were given indeterminate which were confirmed by histopathological examination. Conclusion: In the present study, we had concluded that FNAC is superior to USG for the diagnosis of thyroid lesions.
