An acute stroke from an aortic arch tumor is reported. These tumors are rar
e and have to be differentiated from atheromas. Aortic atheromas commonly p
resent with embolic phenomena and occasionally as masses, Aortic tumors are
more likely to produce obstructive phenomena, presenting as a coarctation
or dissection. Magnetic resonance imaging with gadolinium can facilitate th
e diagnosis. A literature review of aortic masses and their diagnosis and t
reatment are presented.
