CTICasesSpontaneous coronary artery dissection (SCAD) Type 2
Imaging findings
Coronary CTA in a 40-year-old female shows long-segment, smooth, tapering narrowing of the distal LAD with surrounding soft tissue/inflammatory changes representing an intramural hematoma, without a discrete intimal flap.
Key takeaways
Type 2 spontaneous coronary artery dissection (SCAD) presents as diffuse, smooth narrowing due to intramural hematoma without a visible flap. It is a leading cause of MI in young women and is often managed conservatively.
