Intimo-Intimal Intussusception due to Stanford Type A Acute Aortic Dissection Presenting as Cerebral Infarction

Figure 2

Preoperative contrast-enhanced computed tomography. Multiple intimal flaps were present in the aortic root (arrow D in c) and arch (arrows A and B in a) but not in the dilated ascending aorta (arrow C in b), thus constituting a missing flap. A reconstructed coronal image shows discontinuity of the intimal layer in the ascending aorta (arrow C in d) and the intimal flap invaginating the brachiocephalic artery (arrow B in d).
