摘要
目的提高对亚急性肉芽肿性甲状腺炎(SGT)CT表现的认识与诊断。资料与方法回顾性分析8例经外科手术病理证实的SGT,螺旋CT平扫及增强扫描,分析其CT表现。结果SGT的CT表现:甲状腺体积多肿大,一侧多见,甲状腺密度不均匀减低,腺内可见更低或稍低密度结节;根据结节的数目分为单结节型、多结节型和弥漫型;腺内结节边缘模糊,但甲状腺与周围软组织分界清楚,增强扫描轻度或明显不均匀强化。结论甲状腺单侧肿大,腺内见更低或稍低密度结节,结节边缘模糊、密度不均匀,但甲状腺边缘连续完整、清晰是SGT较有特征性的CT表现,结合其典型的临床表现,多能做出正确诊断。SGT是一种自限性疾病,药物治疗有效,如疑本病,可先行药物实验性治疗,不可盲目进行手术切除。
Objective To improve CT diagnosing features of Subacute granulomatous thyroiditis（SGT）. Materials and Methods CT features of 8 cases with SGT proved by surgical and pathology were analyzed retrospectively. Results The features included：swelled thyroids, more frequently located in one lobe, the inhomogeneous low-density node with illegible edge, mild or marked enhancement. SGT was divided into solitary node, multiple-nodes and diffused types. Conclusion One side of swelled thyroid with continued and sharp border,lower-density nodes with dark edge,inhomogeneous density, are some CT characteristics of SGT. Correct diagnosis depended on combining CT features and clinical data. Since SGT is a self limited disease and cured effectively by medicines,a test remedy should be performed firstly instead of surgery.
