摘　　要：目的探讨CT对结节性甲状腺肿(nodular goiters,NG)及其合并症的诊断价值。方法回顾分析我院2007年～2011年经手术病理证实的178例NG及其合并症的CT表现。结果 178例NG及其合并症中,单纯NG51例(28.7%),NG伴腺瘤111例(62.4%);合并桥本甲状腺炎12例(6.7%))合并甲状腺癌15例(8.4%),15例均为甲状腺乳头状癌,其中既合并腺瘤又合并癌的有8例(4.5%),既合并腺瘤又合并桥本甲状腺炎的3例(1.7%)。CT对NG的诊断符合率约为94.4%,NG合并腺瘤诊断正确率约93.7%,而NG合并桥本甲状腺炎或甲状腺癌的CT诊断符合率分别为0及33%。178例NG中65例(36.5%)甲状腺病灶内出现钙化,甲状腺良性病变相关钙化60例(33.7%),与癌相关的钙化只有5例(33.3%),良恶性病变的钙化率差异无统计学意义(P>0.05)。结论单纯NG及NG合并良性病变CT表现具有一定的特征,NG是否合并甲状腺癌CT诊断仍较困难。Objective To explore the CT diagnostic value of nodular goiter （NG）and its complications. Methods CT characteristics of 178 cases with NG and its complications confirmed by surgery and pathology in our hospital from 2007 to 2011 were analyzed retrospectively. Results Of the 178 cases, 15 were diagnosed as papillary carcinomas, （8.4%）, the rest are benign, including 51 pure NG （28.7~）, 111 with adenoma （62.4~） and 12 with Hashimoto thyroiditis （6.7%）, 8 with both adenomas and carcinomas, 3 with both adenomas as well as Hashimoto thyroiditis. The diagnosis accordance rate of CT was 94.4~//oo in NG, 92.3~ in thyroid adenomas, 33~ in papillary carcinomas and 0 in Hashimoto thyroiditis. Among 178 cases, calcification was found in 65 cases （36.5 ~if0）. 60 were benign （33.7~） and 5（33.3~） were malignant, there were no significant difference between benign and malignant cases （ P ~ 0.05）. Conclusion Pure NG and NG with benign lesions have specific features, Whether NG combination with carcinoma is still difficult to diagnose, calcification or not and enhancement can＇t be used as the basis of identifying benign or malignancy.
