@@@@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 (≥5 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.
