Abstract： 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50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(9.40%),2区8例(6.84%), 3区72例(61.54%),4区1例(0.85%),5区3例(2.56%),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(55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.
