目的 分析桥本甲状腺炎 (HT)的CT表现 ,探讨其CT特征。资料与方法 回顾分析经病理证实的 2 4例HT的CT表现 ,并与病理作对照。结果 单纯弥漫性改变 16例 ,CT平扫表现为甲状腺弥漫性肿大 ,密度均匀降低 ,接近软组织密度 ,未见钙化 ,均匀强化。弥漫性改变伴结节 8例 ,其中伴多发结节 3例 ,CT表现为弥漫肿大之甲状腺内见多发结节状稍低密度影 ,边界尚清 ,轻度强化 ;伴单发结节 5例 ,其中 4例合并甲状腺癌 ,轻度增大密度减低的甲状腺内见类圆形低密度影 ,均 <3cm ,边界清 ,除 1例中间有裂隙样更低密度影外 ,余均匀强化 ,3例见低密度圈影环绕。另 1例单发结节为单叶术后病例。结论 HT的CT特征大多为弥漫性肿大 ,密度均匀降低 ,无钙化 ,边缘清楚 ,均匀强化 ;有时伴结节 ,特别是单发结节 ,合并癌的可能性较大
Objective To analyze the CT findings of Hashimoto’s thyroiditis (HT) and discuss its CT features. Materials and Methods Retrospective analysis of pathologically confirmed 24 cases of HT CT performance and pathological control. The results of simple diffuse changes in 16 cases, CT showed diffuse thyroid enlargement, density decreased, close to the soft tissue density, no calcification, uniform enhancement. Diffuse changes with nodules in 8 cases, of which 3 cases with multiple nodules, CT showed diffuse enlargement of the thyroid gland see multiple nodular lesser density, border clear, mild enhancement; with single nodules 5 Cases, of which 4 cases with thyroid cancer, mild increase in the density of the thyroid see the round like low density, were <3cm, clear boundary, in addition to a middle of the crack-like lower density shadow, the more uniform, 3 cases see the low-density ring around. Another case of solitary nodules single leaflet cases. Conclusion Most CT features of HT are diffuse enlargement, uniform density reduction, no calcification, clear edge and uniform enhancement. Sometimes nodules, especially single nodules, are more likely to be combined with cancer
