To Compare Ultrasonography and Fine Needle Aspiration Cytology With a Histopathological Examination in Thyroid Gland Lesions

Background: The thyroid gland is unique among endocrine organs as it is the largest endocrine gland in the body and the rst to develop in fetal life. There is approximately a 4-5% incidence of clinically apparent thyroid lesions in the general population. The goal of the USG and FNAC diagnosis workup now is to select those patients for surgery who have a high likelihood of harboring malignancy in the nodule. Ultrasonography is the single most valuable imaging modality in the evaluation of the thyroid gland. Indications for thyroid USG include evaluation for palpable thyroid lesions or suspected thyroid enlargement and workup of thyroid lesions discovered incidentally. The present study is undertaken to evaluate the utility of FNAC in the preoperative diagnosis of various thyroid lesions and to evaluate the efcacy of in USG and FNAC in differentiating between benign and malignant lesions. Methods: A retrospective clinical study, 50 patients, in the age group of equal to or above 18 years, with thyroid swellings, sent for USG and FNAC at the radiology and pathology department during the period from Results: Out of 50 cases, 76% were malignant, 22% were benign on grey scale ultrasound. Out of 11 malignant cases 10 cases were conrmed malignant by FNAC. Conclusions: High-resolution grey scale ultrasound has emerged as 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.
