CT、超声诊断甲状腺囊性乳头状癌

CT and US in the diagnosis of thyroid cystic papiliary carcinomas

目的探讨以囊性成分为主的甲状腺乳头状癌的CT、超声（US）特征。方法研究分析14例病理证实的甲状腺囊性乳头状癌的CF和US资料。结果所有肿物均有如下CF表现：以囊性为主，内壁有大小不等的实性软组织结节，不均匀明显强化，软组织结节内有沙粒状高密度钙化点或钙化斑。US表现与CT类似：囊性为主，囊内实性突起，突起部分回声不均，甚至有点状强回声（囊内钙化结节）。结论“囊内钙化性结节”征是囊性甲状腺癌可靠的诊断征象之一。

Purpose To investigate the CT and ultrasonographic characterostic characteristic of thyroid cystic papillary carcinoma. Methods CT and ultrasonography (US) of 14 cases with thyroid cystic papillary carcinoma were analyzed. Results In all 14 cases, CT revealed mainly cystic lesions with solid excrescences protruding into the cyst. These nodules were markedly enhanced and contained multiple calcified foci. The appearnce of US was quite similar to CT. Cystic lesion with multiple solid nodules, in which punctate echogenic foci were suggestive of calcification. ConcluSion The ' calcified nodule in cyst' sign was found to be very specific for cystic thyroid carcinoma.
