摘要
目的 :通过螺旋CT与病理大体标本的对照研究 ,探讨甲状腺囊性乳头状癌的CT特征。方法 :行术后肿块病理大体标本的多平面照像 ,然后与相近的病变CT图像相对照 ,以此来研究甲状腺囊性乳头状癌的CT征象。结果 :10例肿物CT表现分为单囊、囊内囊、多囊型三种。单囊表现为一囊性肿物内有实性软组织壁结节 ,结节内、囊内有斑点状钙化 ,结节及囊壁均有强化 ,其囊壁厚薄不均。囊内囊除表现为单囊的征象外 ,最主要表现为为壁结节周围仍有多个小囊与之相连 ,小囊间有分隔 ,粗细不均。多囊型表现为多个大小不一的囊融合在一起 ,其中一个囊内可见实性软组织壁结节及钙化。结论 :囊内钙化性壁结节 ,囊壁厚薄不均 ,壁结节周围可见多个小囊与之相连 ,小囊间有分隔 。
Objective:To evaluate the characteristic sign of papillocystic carcinoma of thyroid by performing a comparative study of spiral CT and pathologic findings.Methods:Postoperative multi-slice pathologic sample were compared with corresponding spiral CT images.Results:With 10 pathologically confirmed cases we can find the following CT signs:single cyst,multi-cyst,cyst within cyst,calcification of the cyst wall,irregularity and calcified solid nodule of the cyst wall.Enhancement of the cyst wall nodule on the wall were showed in all cases.Conclusion:The main feature of papillocystic carcinoma can be summarized as single or multi-cystic lesion with irregular septa.Calcified soft tissue nodule is also a important CT sign of papillocystic carinoma.
