摘　　要：目的:探讨螺旋CT对胸腔入口区结节性甲状腺肿的诊断与鉴别诊断价值。材料与方法:回顾性分析34例胸腔入口区结节性甲状腺肿的CT表现,并与病理对照分析。结果:原发于胸腔入口区结节性甲状腺肿2例,颈部结节性甲状腺肿经胸腔入口延伸于胸内32例。34例中,共检出病变结节63个,单个结节8例(25%),2个以上多发结节26例(75%)。63个结节中,有42个结节向下延伸进入胸腔,其中右侧20个,左侧22个。引起气管不同程度地狭窄者25例,血管受压移位29例,食道受压移位者5例,无1例周围组织受侵犯。结论:螺旋CT对胸腔入口区结节性甲状腺肿的诊断与鉴别诊断是一种有价值的检查方法,增强扫描和三维重建能清楚地显示胸内肿块与颈部甲状腺的关系。Objective： To evaluate spiral CT in the diagnosis and differentiation of nodular goitre at thoracic inlet. Materials and Methods： CT findings in 34 patients with nodular goitres were retrospectively analyzed and were compared with pathological results. Results： Within the 34 cases, 2 cases with nodular goitre primarily located at thoracic inlet, while goitres elongated from cervical thyroid to thoracic inlet in 32 cases. Total 63 nodules were found in 34 patients with nodular goitres. Among them, 42 nodules elongated from cervical thyroid to thoracic inlet in 32 patients. The tracheas were pressed by nodular goitres in 25 patients, and the blood vessels and esophagus were pressed in 29 and 5 patients, respectively. Surrounding organs invaded were not detected in any patients. Conclusion： Spiral CT scanning is a valuable examination in the diagnosis and differentiation of nodular goitre at thoracic inlet, post-contrast scan and 3D reformation help to display the nodular goitre at thoracic inlet, especially display the relationship of nodular goitre with the cervical thyroid.
