摘要
目的 探讨胸腔出入口区的正常CT解剖和CT对该区病变的诊断及鉴别诊断价值。方法 回顾性分析了经病理及临床证实的 117例胸腔出入口区病变的CT表现 ,对 5 0例正常对照组在CT上分为 5个解剖区 :1区 (甲状腺区 ) ;2区 (甲状腺内侧区 ) ;3区 (甲状腺外侧区 ) ;4区 (甲状腺后区 ) ;5区 (甲状腺前区 )。结果 在 117例中 ,病变位于 1区 11例 (9 4 0 % ) ,2区 8例 (6 84 % ) ,3区72例 (6 1 5 4 % ) ,4区 1例 (0 85 % ) ,5区 3例 (2 5 6 % ) ,跨 1、3、5区 15例 (12 8% ) ,跨 1、2、3区 7例(5 98% )。病变多数分布在 3区 ,其中以淋巴结病变最为多见 (5 5例 ) ;甲状腺病变 (32例 )主要分布在 1区和跨区生长。结论 在CT上对胸腔出入口区合理的 5区划分 ,有利于病变的定位和定性诊断 ,具有重要的临床应用价值。
Objective To study the anatomy of the thoracic outlet and inlet,and to evaluate the CT diagnosis and differential diagnosis on abnormal conditions.Methods CT images of 117 pathologically and clinically proved cases in the zones were analyzed retrospectively.Control group contained 50 normal volunteers who were divided into 5 anatomic regions: region 1 (thyroid zone),region 2 (interior thyroid),region 3 (lateral thyroid),region 4 (posterior thyroid),and region 5 (anterior thyroid).Results Of the 117 cases,there were 11 cases (9.40%) in region 1,8 cases (6.84%) in region 2,72 cases (61.54%) in region 3,1 case (0.85%) in region 4,3 cases (2.56%) in region 5,15 cases (12.8%) in transregions (region 1,3,5),and 7 cases (5.98%) in transregions (region 1,2,3).The disorders were mainly distributed in region 3,in which lymphatic node abnormalities were the most common (55 cases).The 32 cases of abnormal thyroid gland were mainly located in region 1 and involved with other regions.Conclusion The 5 regions divided on CT anatomy of the thoracic outlet and inlet are very useful for the localization and definition in the diagnosis,which have important clinical value.
