目的:观察结节性甲状腺肿CT表现,探讨结节性甲状腺肿的CT特征。材料和方法:回顾性分析了52例经手术病理证实的结节性甲状腺肿的CT表现,并与病理所见作对照研究。结果:根据52例结节性甲状腺肿的CT表现,将其分为弥漫型和局限型两种类型,弥漫型38例(双侧16例,单侧22例),局限型14例(多发8例,单发6例)。15例弥漫型病变伴大范围囊变者,囊壁环状强化,厚薄不均,壁结节强化,囊内呈岛状强化,是结节性甲状腺肿的特征性表现,而病灶密度、钙化、延伸范围、对气管血管压迫情况只可作为诊断的参考依据。结论:CT扫描特别是增强及薄层扫描对诊断结节性甲状腺肿具有重要价值,并能评价其与周围结构的关系。
Objective: To observe the CT findings of nodular goiter and explore the CT features of nodular goiter. Materials and Methods: CT findings of 52 cases of nodular goiter confirmed by surgery and pathology were retrospectively analyzed and compared with the pathological findings. Results: According to the CT findings of 52 cases of nodular goiter, they were divided into two types: diffuse type and localized type, diffuse type in 38 cases (bilateral in 16 cases, unilateral in 22 cases) and localized type in 14 cases (multiple 8 Cases, single hair 6 cases). 15 cases of diffuse lesions with large-scale cystic degeneration, ring-like cystic wall enhancement, uneven thickness, wall nodules enhanced intracapsular island-like enhancement is characteristic of nodular goiter, and the lesion density, calcification , Extended range of tracheal vascular compression can only be used as a diagnostic reference. Conclusion: CT scan, especially enhanced and thin-section scan, is of great value in the diagnosis of nodular goiter and can evaluate its relationship with the surrounding structures.
