胸腔出入口区CT研究

CT studies of the thoracic outlet and inlet

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 ,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% )。病变主要分布在 3区 ,其中以淋巴结病变最为多见 (5 5例 ) ;甲状腺病变(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划分 5个解剖区 ,有利于病变的定位和定性诊断 。

Objectives:The anatomys of the thoracic outlet and inlet and the valuation of CT diagnosis and differential diagnosis on abnormal conditions were studied. Methods: CT imaging of 117 cases proved pathologically and clinically in the zones were analysized, retrospectivelly. Control group was 50 normal cases divided into 5 anatomic regions: 1 region (thyroid zone), 2 region(interior thyroid), 3 region (lateral thyroid), 4 region (posterior thyroid), 5 region (anterior thyroid). Results: In 117 cases, 1 region 11 cases (9.40%), 2 region 8 cases (6.84%), 3 region 72 cases (61.54%), 4 region 1 case (0.85%), 5 region 3 cases (2.56%), transregional (1, 3, 5) 15 cases (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. Conclusions: On CT anatomic regions of the thoracic outlet and inlet divided into 5 zones were very useful for localization and definition of diagnosis, which have the important valuation of clinical uses.
