A 62 year-old male HTA patient with an aliasing cystic lesion close by his prostate without urogenic symptom was revealed by Doppler technique. A note of an pseudoaneurysm of the right internal iliac artery due to A-V fistula is written down, but it has been missed out on it in 3 other examinations in the past.

MSCT and Angio confirm the pseudoaneurysm of right internal iliac artery.
After a vascular collation via pelvic angiography the pseudoaneurysm disappeares.
Without Doppler technique we could be in error or misdiagnose some cystic lesion.
