Radio-Cytopathologic Correlation Of The Thyroid Nodule

Background: Ultrasonographic features of thyroid nodule are very helpful in predicting the risk of thyroid cancer. Fine-needle aspiration (FNA) is the primary diagnostic methodology used for thyroid nodule evaluation. Presence of ultrasonographic future suggestive of non-benign thyroid nodules may consider a way to decide which nodules should be sampled and subsequently, reduce the unnecessary biopsies. Of note up to one third of fine needle aspiration biopsies may be non-diagnostic, requiring open surgical biopsy for diagnosis. The current study aimed to correlate the ultrasonographic findings of thyroid nodule with malignancy. Methods: Retrospective cohort study was performed at King Salman Armed Forced Hospital to evaluate ultrasonographic finding in relation to cytology and histopathology. Result: Cytology results in relation to ultrasound finding show that malignancy was associated with larger nodule size, nodules containing intranoduler blood supply as well as irregular nodular border. Conclusion: Radiological assessment of thyroid nodule by experience radiologist in thyroid sonography is encouraged looking for high risk radiological finding suggestive of malignant thyroid nodule such as large, hypo echoic, irregular nodule.
