CTICasesSpontaneous coronary artery dissection (SCAD) with intramural hematoma
Imaging findings
Coronary CTA demonstrates a circumferential, crescentic soft tissue thickening around the ostium of the left main coronary artery, causing caliber narrowing and compression of the true lumen.
Key takeaways
Spontaneous coronary artery dissection (SCAD) can present as an intramural hematoma, seen as a soft tissue crescent compressing the coronary lumen on coronary CTA. Distinguishing it from vasculitis relies heavily on acute clinical presentation.
