Infrarenal Abdominal Aortic Cystic Adventitial Disease Detected on Ultrasound and Magnetic Resonance Imaging.

Here, we describe a case of an asymptomatic 55-year-old male patient who underwent an abdominal ultrasound examination which showed a para-aortic anechoic lesion without color Doppler signals. A previously performed magnetic resonance imaging examination showed a cystic lesion with features consistent with cystic adventitial disease. To the best of our knowledge, this is the first case of abdominal aortic cystic adventitial disease detected with ultrasound and magnetic resonance images.
