摘　　要：目的探讨主动脉壁内血肿CT表现及其鉴别诊断。方法分析15例主动脉壁内血肿256层螺旋CT血管成像特征。结果 15例主动脉壁内血肿A型6例,B型9例,直接征象:主动脉壁环形或新月形增厚,无内膜破裂;间接征象:主动脉粥样硬化、内膜钙化内移、内膜渗漏、穿透性溃疡。结论主动脉壁内血肿256层螺旋CT表现具有特征性,需与其它病变鉴别。Objective To investigate the 256-slice helical CT appearance and differential diagnosis of aortic intramural hematoma （AIH）. Methods The characteristics of the 256-slice helical CT finding in 15 cases of AIH were analyzed. Results Six patients were diagnosed as Stanford type A, and the others as type B. The direct feature of AIH included crescent or circular thickening （〉15 mm） of the aortic wall without signs of lumen formation resulting from intimal rupture. The indirect feature included atherosclerosis, calcification ingression, penetrating ulcer, and leakages. Conclusion The 256-slice helical CT appearance of AIH has characteristic, AIH must bedifferentiated with others.
