An unusual case of aortic valve obstruction

Summary During a dissection class for anatomy, a white lipoid mass was found in the ascending aorta, which was partly attached to the wall and fi lled the sinuses of Valsalva and almost fi tting as a cast. This mass prevented full opening of the mobile aortic valve leafl ets, thereby causing an obstruction. Microscopic analysis revealed fi bres and presence of polymorphonuclear white blood cells. It seems reasonable to assume that this mass has formed in the last weeks or months of the life of this subject, which is much quicker than for calcifi ed aortic valve stenosis. Therefore, signs and symptoms of aortic obstruction might have been missed or misinterpreted. In case of timely detection during life, diagnostic imaging and therapeutic approach can be challenging.
