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,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 (12.8%),跨1、2、3区7例(5.98%)。病变主要分布在3区,其中以淋巴结病变最为多见(55例);甲状腺病变(33 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五区划分,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： The anatomys of the thoracic outlet and inlet and the valuation of CT diagnosis and differential diagnosis on abnormal conditions were studied.Method： CT imaging of 117 cases proved pathologically and clinically in the zones were analysized, retrospectlvelly.Control group was 50 normal cases divided into 5 anatomic regions; 1 region （thyeoid Zone）, 2 region （interior thyroid）, 3 region （Lateral thyroid）, 4 region （posterior thyroid）, 5 region （anterior thyroid） .Results; In 117 cases, 1 region 11 eases （9.40 % ）, 2 region 8 easws （6.48 % ）, 3 region 72 cases （61., 54 % ）, 4 region 1 case （0.85 % ）, 5 region 3 eases （2,56%）, trarmregional （1, 2, 5） 15 eases （12.8%）, transregional （1, 2, 3） 7 cases （5.98%） .The disorders were mainly distributed in 3 region in which lymphatic node abnormalities were the most of them （55 cases） .The 33 cases of abnormal thyroid gland were mainly in the 1 zone and involved with other zones. Conclusion; On CT onatomie regions of the thoracic oudet and inlet vivided into 5 zones were very useful for localization and definition of diagnosi, which have the important valuation of clinical uses.
