摘　　要：目的:探讨甲状腺肿瘤的CT诊断价值。方法:回顾性分析行CT检查并经手术病理证实的36例甲状腺肿瘤的CT资料,36例均行平扫,26例加作增强。结果:36例甲状腺肿瘤中,甲状腺腺瘤10例,均有完整包膜,无淋巴结转移;甲状腺癌26例,22例为乳头状癌,3例为滤泡状癌,1例为胸内甲状腺未分化癌。12例有细钙化及小斑点状钙化,20例边界不清,侵犯周围组织器官。15例颈部淋巴结转移。结论:注意肿瘤的钙化、肿瘤与正常甲状腺组织及周围结构的关系,以及有无淋巴结和远处转移是判断甲状腺肿瘤良恶性的主要依据。CT对甲状腺肿瘤的诊断和鉴别诊断有较重要的应用价值。Objective： To explore the value of CT scan on diagnosis of thyroid tumors. Methods： Thirty six cases of thyroid tumors proved by surgery or pathological data were analyzed, retrospectively. All of them were examined by plain CT scan, of 26 were additionally examined by enhance scan. Results. Among 36 cases, ten thyroid adenomas had a complete capsule and no metastatic lymph node. Among 26 thyroid carcinomas, 22 were papillary carcinoma, 3 were folliculla carcinoma, 1 case was undifferentiated carcinoma, of 12 cases were found calcification, including fine granular calcifications and small calcification, 20 cases had unclear margin and infiltrative growth, 15 cases were revealed metastatic lymph node in the neck. Conclusion： The calcification in lesions, the relationship between the lesions and normal thyroid tissue or surrounding structures and cervical metastatic lymph nodes or metastasis is main point for CT diagnosis and differential diagnosis in thyroid tumors. CT scan might take an important value on diagnosis and differential diagnosis in thyroid tumors.
