摘　　要：目的分析CT对结节性甲状腺肿以及合并甲状腺癌的鉴别诊断的作用。方法回顾分析经手术病理证实的47例结节性甲状腺肿的CT表现。结果根据47例结节性甲状腺肿(其中12例合并甲状腺癌,均为乳头状癌)的CT表现,将其分为弥漫型、多结节型和单结节型三种类型,弥漫型12例(合并甲状腺癌3例)、多结节型22例(合并甲状腺癌9例)、单结节型13例。结论结节性甲状腺肿的特征性表现为多发不规则形混杂密度病灶,内部合并有囊变,囊壁环状强化,厚薄不均,壁结节轻中度强化,结节性甲状腺肿合并甲状腺癌的癌灶位于甲状腺边缘,出现相邻结构侵犯和颈部淋巴结转移易于诊断,具有一定特征性。Objective To study CT features of nodular goiter complicating with thyroid carcinoma,improve the diagnostic accuracy.Methods The CT finding in 47 patients with nodular goiter confirmed by pathology were analyzed.Results On basis of the 47 patients with nodular goiter（12 cases with thyroid carcnoma）.The CT findings of nodular goiter could be classified into diffusion 12 cases（3 patients with thyroid carcinoma）,multinodular type 22 cases（9 patients with thyroid carcinoma）,mononodular type 13cases.Conclusions CT features of nodular goiter have multilocal heterodensities,that mononodule was markedly homogenic enhanced and cystic wall and intracystic nodular enhanced as the pace of thyroid.If the carcinoma lesions of nodular goiter lied in the margin of the Thyroid,CT was of great value in the diagnosis.
