From: Arterial dissection in childhood Takayasu Arteritis: not as rare as thought
Vascular imaging in the three children with Takayasu arteritis and dissection. Legend: Patient 1: a A coronal reformat of the 3D volume rendered MRA dataset demonstrates the intramural hematoma (arrow) as well as a dissection flap (arrowhead) at the caudal end of the aneurysm (*) in the abdominal aorta. The intramural hematoma (arrow) is located at the proximal end of the aneurysm. The celiac axis arises immediately distal to the dissection flap with a stenotic origin. There is thickening of the aortic wall and a long-segment narrowing of the infra-renal aorta. Patient 2: b A T2 weighted turbo spin echo magnetic resonance image in the axial orientation shows a dissection flap in the thoracic descending aorta at the level of the left atrium (arrow). Patient 3: c The T1 weighted turbo spin echo and d the para-coronal reformat of a contrast-enhanced magnetic resonance angiogram show an aneurysm of the right carotid artery (*) with intramural hematoma (arrow). CC = Common carotid artery, IV = innominate vein
