Imaging of a Renal Artery Aneurysm Detected Incidentally on Ultrasonography

Abstract EN

Renal artery aneurysms occur with a frequency of less than 1% of the general population.

Even if they are usually asymptomatic and incidentally found, they can be complicated with life-threatening conditions like rupture, thrombosis, embolism, or hypertension.

Thus, once diagnosed, they should be fully evaluated with further imaging and treated when indicated.

We present the case of a patient who was referred for ultrasonography for an unrelated reason.

The examination demonstrated a hyperechoic focus near the right kidney.

Further imaging workup with MDCT established the diagnosis of a right renal artery aneurysm which was saccular in shape and peripherally calcified.

This ring-like calcification was also visible in a KUB radiography which was also performed.

After presenting the case, various aspects of this rare entity are discussed.
