Abstract
<p class="first" id="d2314861e127">Spontaneous coronary artery dissection (SCAD) is
a rare cause of acute myocardial
ischemia. Identification of intimal flap, true and false lumens in coronary angiogram
(CAG) is the standard method to diagnose SCAD. In cases of obscure intimal flap, intravascular
ultrasound (IVUS) is a useful method to diagnose, although crossing the wire and IVUS
in the dissected lesion is invasive. Multidetector computed tomography (MDCT) provides
valuable information in any clinical setting less invasively. We report here a rare
case of spontaneous dissecting coronary artery pseudoaneurysm diagnosed by CAG and
MDCT, healed by medical treatment, and followed up by MDCT over a 2-year period.

<b>Learning objective:</b> Spontaneous coronary artery dissection (SCAD) is usually
diagnosed by the findings
of intimal flap, true and false lumens in coronary angiogram (CAG). In case intimal
flap is not obvious in CAG, intravascular ultrasound (IVUS) is a useful method to
diagnose, although crossing the wire and IVUS in the dissected lesion is invasive.
Multidetector computed tomography is an alternative useful method to obtain valuable
information to diagnose SCAD less invasively.>
