Coronary aneurysms are uncommon. The most frequent etiologies are atheroscl
erotic and congenital, although there are several other rare causes. Myocar
dial infarction and sudden death may be the initial manifestations which ar
e usually a consequence of aneurysm complications such as rupture or distal
embolization. Although coronariography is the gold standard diagnostic tec
hnique, coronary aneurysm may also be detected by non-invasive methods such
as ultrasonography and nuclear magnetic resonance.
We report the case of a young male with hypercholesterolemia who presented
cardiac arrest as the first clinical manifestation. Ultrasonography and MRI
revealed the presence of multiple coronary aneurysm. This case illustrates
the usefulness of non-invasive techniques for the diagnosis of coronary an
eurysm.
