title: Pseudotumor of the renal pelvis caused by renal artery aneusysm.
abstract: Urographic abnormalities caused by renal artery aneurysms are discussed on the basis of seven cases. Angiography is the diagnostic procedure of choice to make the correct diagnosis. In cases of completely thrombosed aneurysms angiography may only demonstrate an avascular mass with displacement of vessels. At ultrasound examination renal artery aneurysms should be included in the differential diagnosis of echo-free renal masses.
