 The diagnostic coronarography showed an asymmetric and significate coronary calcification of the ostium and the initial part of the right coronary ( Fig. 1 ).

After two runs, and without any clinical symptoms, the injection control revealed an extravasation of the iodinated contrast to the ascending aorta ( Fig. 2 ), which was related to ostial right coronary dissection.

Thinking that the aortic hematoma was driven by the ostial right coronary dissection with retrograde extension to the aortic wall, we immediately decided to implant a drug-delivery stent (ORSIRO 3 x 13 mm, Biotronik) in the ostium and the proximal segment of the right artery to seal the artery dissection ( Fig. 3 ) and stabilize the aortic IMH. 
Initial no injected CT-scan: contrast extravasation from ostial right coronary to ascending aorta.

 A CT scan of the ascendant aorta was performed directly after the procedure ( Fig. 4 ) and found no aortic dissection (AD) but an aortic IMH, going from the ostial right coronary (with contrast product extravasation) to the arch of the aorta (5 mm thick).
Day 7 with injected CT-scan: aortic hematoma resorption without contrast extravasation.

 The second CT scan control on day 7 ( Fig. 5 ) showed total resorption of aortic hematoma.
