结节性甲状腺肿的CT诊断

目的分析结节性甲状腺肿CT表现的病理基础,探讨结节性甲状腺肿的CT特征,提高术前诊断正确率.方法回顾分析经手术病理证实的46例结节性甲状腺肿的CT表现,并与病理对照.结果笔者根据结节性甲状腺肿的CT特点,将其分为多结节型、单结节型、囊肿型.多结节型CT的诊断准确率高.单结节型均匀明显强化,囊肿型增强后囊壁、壁结节与周围甲状腺组织同步强化,为结节性甲状腺肿特征表现.蛋壳样钙化多见于结节性甲状腺肿.结论 CT对结节性甲状腺肿的诊断具有很高的价值.

CT Diagnosis of Nodular Goiter

Objective To study CT features and pathological basis of nodular goiter and to improve the diagnostic accuracy of nodular goiter. Methods The CT finding in 46 patients with nodular goiter confirmed by pathology were retrospectively analyzed, compared with pathological findings. Results The CT findings of nodular goiter could be classified into multinodular type, mononodular type and cystic type. The multinodular type could be identified accurately by CT. It is CT features that mononodule was markedly homogenic enhanced and cystic wall and intracystic nodular enhanced as the pace of thyroid. The eggshell like calcification usually occurred in nodular goiter. Conclusion CT was of great value in the diagnosis of nodular goiter.
