The Role of Conventional Ultrasound in the Assessment of Thyroid Nodule in Erbil City

摘要

Background: Nodular thyroid disease is relatively common although thyroid cancer is rare. The aim of this study is to evaluate the advantage and reliability of conventional ultrasound in correlating sonographic characteristics of thyroid nodule with US-FNAC guided result as a diagnostic aid in thyroid nodule. Method: 111 patients were examined by ultra sound and FNA done in Rizgary teaching hospital department of radiology from May 2015 – July 2016. Result: 9% (10 of 111) patients have malignant features by ultrasound which are include hypoechogenicity, border irregularity, ill defined out line, presence of micro calcification, halo sign not continues. 7 of them were proved malignancy by FNA. The specificity, sensitivity and accuracy of US-FNA were 96.2 %, 85.7% and 95.5% respectively. Conclusion: These ultrasound features aid in prediction the benign or malignant nature of given nodule but no single ultrasound criterion is reliable in differentiation all benign from malignant thyroid nodule.
