A case of spontaneous coronary artery dissection complicated with pseudoaneurysm healed by medical treatment: Follow-up by multidetector computed tomography.

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. <Learning objective: 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.>.
