Abstract
Background: To determine the various sonographic findings in a papillary carcinoma of the thyroid. Materials and Methods: 48 patients with a proven papillary carcinoma of the thyroid were involved. The sonographic features analyzed were the size, shape, content, margin, internal echo, and calcification pattern. Results: Common sonographic features of a papillary carcinoma include the hypoechoic texture (94%), an ill defined margin (81%), a solid nodule (100%), irregular shape (48%), and microcalcifications (35%), or no calcifications (42%). The uncommon features included a hyperechoic or mixed echo texture, cystic elements, a well defined margin, and a coarse or peripheral calcifications. Conclusion: Ill-defined hypoechoic solid nodule with microcalcification is a characteristic ultrasonographic finding of a thyroid papillary carcinoma.
유방암 검사와 함께 시행한 갑상선 선별 초음파 검사에서 나타난 전형적인 갑상선 유두암의 소견은 경계가 불분명한 고형의 저에코 결절로 나타나고 점상 혹은 미세석회화를 보일 수 있어 이러한 결절에서는 조직 검사를 통한 확진이 필요하다.
