CT DIAGNOSIS OF AN UNUSUAL AORTIC DISSECTION WITH INTIMOINTIMAL INTUSSUSCEPTION - THE WIND SOCK SIGN

A unique combination of CT findings is reported in a rare case of aort ic dissection with intimointimal intussusception. The CT showed a wind sock-like appearance in the contrast column of the aortic arch, which was felt to be characteristic of the intussusceptum. Complementary CT findings, including proximal flap in the dilated root of the aorta, n o midascending aortic flap, a descending aortic flap, and pericardial effusion, enabled establishment of the preoperative diagnosis.
