目的探讨结节性甲状腺肿和甲状腺腺瘤的CT表现。方法回顾性分析43例(43对)甲状腺病变患者的临床资料,其中结节性甲状腺肿29例,甲状腺腺瘤14例。结果结节性甲状腺肿29例(29对)CT检查发现,弥漫型28个,其中单侧6个双侧22个;局限型30个,其中单发12个,多发18个。结节性甲状腺肿典型CT表现为环形钙化、双环征、病灶内间隔线及壁结节征象。甲状腺腺瘤14例(14对)CT检查发现,病灶均为单侧、单发病灶,典型CT表现为内缘光整的完整强化环(单环征)。结论通过特异性CT表现提高对结节性甲状腺肿与甲状腺腺瘤的诊断质量,对临床诊断与治疗方式的选择均有显著意义。
Objective To investigate the CT findings of nodular goiter and thyroid adenoma. Methods Retrospective analysis of 43 cases (43 pairs) of thyroid lesions in patients with clinical data, including 29 cases of nodular goiter, thyroid adenoma in 14 cases. Results Of the 29 cases (29 pairs) with nodular goiter, 28 were diffusely typed, of which 26 were unilateral and 6 on both sides and 30 were limited, of which 12 were single and 18 were multiple. The typical CT findings of nodular goiter are ring calcification, bicyclic sign, interstitial septum and wall nodules signs. Thyroid adenoma in 14 cases (14 pairs) CT examination found that the lesions were unilateral, single lesions, the typical CT showed a complete enhancement of the rimmed enhanced ring (single ring sign). Conclusion The diagnosis of nodular goiter and thyroid adenoma is improved by specific CT findings, and the choice of clinical diagnosis and treatment is significant.
