Demonstration of cystic adventitial disease by intravascular ultrasound imaging

In a 34-year-old woman with intermittent calf claudication, cystic adventitial disease of the popliteal artery was demonstrated by intravascular ultrasound imaging. Multiple intramural cystic masses were seen to be compressing the arterial lumen. The diagnoses of cystic adventitial disease was confirmed by surgery. Intravascular ultrasound imaging reliably identifies cystic adventitial disease; its application can be recommended as an alternative to established diagnostic procedures (computed tomography, magnetic resonance imaging) in patients undergoing angiography.
