Thyroid nodules are extremely common. It found in 4–8% of adults by population, 10–41% by ultrasound, and 50% at autopsy. High resolution ultrasound is the primary imaging modality for the evaluation of these nodules. 150 patients with thyroid nodules were taken in our study. 11 were males and 139 were females approximately 189 nodules were detected sono graphically in 150 patient. Nodules less than 1cm and purely cystic lesion were excluded from our study. Most of the FNAC were performed under USG guidance and histo-pathological findings were considered as final diagnosis. Cystic lesions were found to be benign. Hyper echoic & round shape lesions were found to be benign. Calcified lesions have more chance of malignancy. 22.1% calcified lesion were found in benign lesions. Calcified lesions are further divided into micro & macro according to their sizes. Micro calcified lesions were found to be malignant lesion (approx. 83 %). To summarize, gray scale USG findings of thyroid nodules were helpful in identifying clinically significant nodules and to differentiate between malignant and benign nodules. Our study revealed, the malignant features of poorly defined margins, micro calcification, marked hypo echogenicity and cystic predominance nature were found to have high diagnostic accuracy for the identification of malignant thyroid nodules while benign lesions demonstrated solid consistency, well defined margins and regular halo.
