CTICasesSpontaneous Coronary Artery Dissection in Fibromuscular Dysplasia
Imaging findings
Coronary CT angiography shows severe narrowing of the right coronary artery lumen with an eccentric soft-tissue cuff representing intramural hematoma. The patient has fibromuscular dysplasia (FMD) and a prior spontaneous dissection of the left system.
Key takeaways
Spontaneous coronary artery dissection (SCAD) is a non-traumatic, non-atherosclerotic tear in the coronary wall, leading to intramural hematoma. It is strongly associated with systemic arteriopathies such as fibromuscular dysplasia (FMD) and has a high rate of recurrence.
