title: Intimo-intimal intussusception of the aorta.
abstract: A 50-year-old man presented with acute onset of chest pain. Subsequent transesophageal echocardiography and computed tomography scan showed absence of a flap in the ascending aorta and a clear dissection flap involving the arch and descending aorta. Magnetic resonance imaging showed a tear and a small flap in the right coronary sinus. During surgery, we found a total circumferential intimal tear at the sinotubular junction with intimo-intimal intussusception of the internal channel into the arch. Dissection without intimal flap and aortic intussusception is a rare form of type A dissection, which is difficult to diagnose on routine investigations and can delay treatment.
