摘要
目的:探讨主动脉壁内血肿(IMH)的MSCT影像学征象及诊断价值。方法:回顾性分析31例主动脉壁内血肿的MSCT图像,包括平扫图像及增强图像。结果:31例主动脉壁内血肿,15例为A型,16例为B型。MSCT主要表现为:1主动脉壁呈环形或新月形增厚,增厚血肿壁2.5~24mm不等,13例患者检出主动脉内壁溃疡;220例出现了心包积液和/或胸腔积液,12例显示出内膜钙化斑内移,31例均出现了延迟显像浆膜面强化。结论:MSCT平扫及增强检查可清楚显示血肿的部位、累及范围、血肿程度以及并发间接征象,可对主动脉壁内血肿进行明确诊断及鉴别诊断。
Purpose:To investigate the value of MSCT in the diagnosis of aortic intramural hematoma(AIH).Methods:The routine CT and CT angiography findings of 31 cases with aortic intramural hematoma were retrospectively analyzed.Results:Fifteen cases were diagnosed as Stanford A AIH,while the other 16 cases were diagnosed as Stanford B AIH.The MSCT findings showed as follows:circular or crescentic thickening(2.5-24mm);penetrate ulcer(13 cases);pericardial effusion or/and pleural effusion(20 cases);displaced intimal calcifications(12 cases);delayed enhancement of aorta serous membrane(31 cases).Conclusion:The location,extent,thickness and complications of aortic intramural hematoma can be clearly displayed by MSCT,thereby valuable information for diagnosis and differential diagnosis can be provided.
