Coronary angiography and subsequent 3-D reconstruction of an abdominal-pelvic CTA performed as part of screening for FMD in a 52-year-old woman with anterior STEMI due to SCAD. (A) Left coronary angiography in a cranial projection with a long segment (between white arrows) of abrupt luminal compression by intramural hematoma affecting the distal left anterior descending artery (type 2 SCAD). (B) FMD (beading) of both main renal arteries (white asterisks) and more distally, FMD (beading) involving both external iliac arteries (between white arrows) was observed. CTA, computed tomography angiography; FMD, fibromuscular dysplasia; SCAD, spontaneous coronary artery dissection; STEMI, ST-elevation myocardial infarction.
