摘要
目的:探讨亚急性甲状腺炎的CT表现和特点,提高对该病影像表现的认识。材料和方法:回顾性分析10例亚急性甲状腺炎CT影像特征及临床资料,共16个病灶,其中9例经手术病理证实,1例临床证实。同时抽取局限型甲状腺癌65例,就部分征象作对照分析。结果:亚急性甲状腺炎局限性3例,弥漫性7例。CT表现分3型:①局限于甲状腺一侧叶的低密度病变,病变甲状腺肿大,峡部可受累,3例;②甲状腺两叶各有一低密度病变,呈不对称肿大,病灶之间有正常甲状腺组织,6例共12个病灶;③甲状腺两叶及岬部均匀肿大,略不对称,1例。CT平扫病变为低密度,增强扫描后呈轻到中度均匀强化(15/16),腺内更低密度结节少见(1/16)。病变处甲状腺边缘模糊(16/16),与正常甲状腺组织界限不清(15/16),而局限型甲状腺癌病灶与正常甲状腺腺组织分界清楚(62/65),两者极不一样(P<0.01)。结论:亚急性甲状腺炎CT表现有一定特点,熟悉这些特点对于诊断及鉴别诊断很有帮助。
Purpose：To explore the imaging features of subacute thyroiditis. Materials and Methods： CT imaging findings and clinical data of 16 lesions in 10 patients of subacute thyroiditis were reviewed. Those of 65 cases of thyroid carcinoma and were also analyzed as contrast groups. Results： Subacute thyroiditis appeared as focal（n = 3） or diffnse（n = 7） enlargement of thyroid gland which was slightly homogenonsly enhanced after the administration of contrast media（n = 9, which include totally15 lesions） on CT scan, focal hypoattenuated nodules inside the lesion was rare（n = 1）, the margin of each lesion was indistinct from the normal thyroid tissues（15/16）, but clear in carcinoma（62/65）in contrast, P 〈 0.01. The main CT findings were as follows： ① Focal lesion or unilateral thyroid lobe enlargement with decreased attenuation （n = 3） . ②Enlargement of both lobes of thyroid with focal lesions separated by normal tissues （n = 6） ③diffnsed enlargement of thyroid gland with homogenonsly decreased attenuation（n = 1） . Conclusion： Subacute thyroiditis showed some special CT features, recognizing these specific features is helpful in the diagnosis of subacute thyroiditis and differentiation of thyroid lesions.
