亚急性甲状腺炎的CT表现

CT features of the subthyroiditis (analysis of 9 cases)

目的 探讨CT在亚急性甲状腺炎的诊断和鉴别诊断中的价值。方法 回顾性分析9例亚急性甲状腺炎患者的临床资料和CT图像。所有病人均为女性,年龄在20—45岁之间,平均37岁,以颈部肿痛、甲状腺肿块或结节行CT检查。结果 首次CT均示甲状腺肿大或伴结节,密度不均匀性减低,增强扫描密度不均反而不明显,多位于一侧;病变具有自限性且易反复发作,复查病例中多见病侧消失或好转而对侧又发生病变,抗炎加糖皮质激素治疗效果佳。结论 CT可作为亚急性甲状腺炎诊断和鉴别诊断的一种辅助手段。

Purpose To evaluate computed tomography (CT) imaging for diagnosis and differentiation of the sublhyroiditis. Methods CT images of nine subthyroiditis patients confirmed by clinical practice and experimental data were retrospectively analysed. All patients underwent CT plain, scans and contrastment scans performed in three patients consecutively. four cases of them receives following CT examination one to two times after the treatment of antiinilammation and glucocorticoids. Results Thyroid swelling, lower density and abnormal modules could be shown in CT images . Most of lesions occured unilaterally, but they could shift to another side in the developing stage. Abnormal CT features disappeared after effective treatment. Conclusion computed tomography technique offers additional valuable means, besides laboratory examination, ultrasonography and nuclear medicine, for diagnosis and differentiation of sublhyroiditis.
