Abstract :

• The thyroid gland is the largest of all endocrine glands and is the only one which is amenable to direct physical examination because of its superficial location which allows excellent visualization and evaluation of its normal anatomy and pathologic condition by high resolution real-time grey-scale sonography. The aim is to evaluate the utility of FNAC in preoperative diagnosis of various thyroid lesions and to evaluate the efficacy of in USG and FNAC differentiating between benign and malignant lesions. The goal of USG and FNAC diagnosis work up now is to select those patients for surgery who have a high likelihood of harboring malignancy in the nodule. • Materials and Methods:  This prospective study was carried out on 100 patients who came to our department from period of June2019 to May2020.Grayscale ultrasound of neck followed by USG guided FNAC of thyroid swelling in 100 patients, in the age group of equal to or above 18years. • Results:  Out of 100 cases,2% were malignant,94% were benign and 4%were indeterminate lesions on greyscale ultrasound. All the 2 malignant cases were correctly diagnosed as malignant on pathology. Out of 94 benign as a hypo echoic lesion with well defined margin and coarse calcification. Due to coarse calcification they were diagnosed as benign on ultrasonography but turned out to be malignant on pathology as papillary carcinoma. Out of 4 indeterminate cases, 0 cases proved to be malignant and 4 cases benign on pathology • Conclusion:  High resolution grayscale ultrasound has emerged as an initial imaging modality of choice for the evaluation of patients with thyroid enlargement. Ultrasound can detect solitary nodule, multiple nodules and diffuse thyroid enlargement .It can also differentiate solid and cystic lesions.
