甲状腺病变的CT诊断和鉴别诊断

目的：分析甲状腺病变的CT表现,探讨各种甲状腺病变的CT诊断和鉴别诊断要点。方法整群收集该院2009年11月—2015年12月经临床和病理证实的甲状腺病变共54例的CT资料,进行回顾性分析。结果该组54例中,甲状腺腺瘤24例,甲状腺癌15例,结节性甲状腺肿8例,桥本氏甲状腺炎4例,甲状腺囊肿2例,Graves病1例。该组病例依据其CT表现,分为三大类型：①单结节型33例,包括甲状腺腺瘤17例,结节性甲状腺肿2例,甲状腺癌12例,甲状腺囊肿2例；②多结节型16例,包括结节性甲状腺肿6例,甲状腺腺瘤7例,甲状腺癌3例；③弥漫肿大型5例,包括Graves病1例,桥本氏甲状腺炎4例。结论甲状腺病变CT分型、CT平扫和增强特点,与正常甲状腺组织及周围关系,以及有无颈部淋巴结肿大转移是甲状腺病变定性诊断的主要依据。

CT Diagnosis and Differential Diagnosis of Thyroid Lesions

Objective To analyze the CT manifestations of thyroid lesions and to explore the CT diagnosis and differential diagnosis of various thyroid lesions. Methods Group selection the CT data of 54 cases of thyroid diseases confirmed by clinical and pathological changes in our hospital from November 2009 to December 2015 were retrospectively analyzed. The data of 54 cases were collected and analyzed. Results In the group of 54 patients, 24 cases of thyroid adenoma, 15 cases of thyroid carcinoma, 8 cases of nodular goiter, 4 cases of Hashimoto's thyroiditis,2 cases of thyroid cyst, Graves disease in 1 case. This group of cases according to the CT performance, is divided into three types: ① Single nodular type of 33 cases, including 17 cases of thyroid adenoma, 2 cases of nodular goiter , 12 cases of thyroid carcinoma,2 cases of thyroid cyst ; ②16 cases of multiple nodular type, including nodular goiter in 6 cases, 7 cases of thyroid adenoma, and 3 cases of thyroid carcinoma; ③ Diffuse swelling in 5 cases, including Graves disease in 1 case , Hashimoto's thyroiditis in 4 cases. Conclu-sion Thyroid lesions on CT classification, CT scan and enhanced features, and normal thyroid tissue and the surrounding re-lation, and with or without cervical lymph nodes metastasis is the main basis for the qualitative diagnosis of thyroid lesions.
