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 investigate the value of spiral CT in the diagnosis and differential diagnosis of nodular goiter in the thoracic cavity. Materials and Methods: The CT findings of nodular goiter in 34 cases of thoracic cavity were retrospectively analyzed and compared with the pathology. Results: The primary nodular goiter in the thoracic entrance area in 2 cases, neck nodular goiter through thoracic cavity extension in the thorax in 32 cases. Of the 34 cases, 63 lesions were detected, 8 (25%) were single nodules and 26 (75%) were multiple nodules of more than two. Of the 63 nodules, 42 nodules extend downward into the chest, with 20 on the right and 22 on the left. 25 cases of tracheal stenosis caused by different degrees, 29 cases of vascular compression shift, esophageal pressure displacement in 5 cases, none of the surrounding tissues were infringed. Conclusion: Spiral CT is a valuable method for the diagnosis and differential diagnosis of nodular goiter in the thoracic portal region. Enhanced scanning and three-dimensional reconstruction can clearly show the relationship between the thoracic mass and the neck thyroid.
