Idiopathic renal artery and infrarenal aortic aneurysms in a 6-year-old child: Case report and literature review

Multiple arterial aneurysms are distinctly rare in the pediatric population. Most arterial aneurysms in children are secondary to infections, trauma, arteritides, collagen vascular diseases, and other causes. True idiopathic aneurysms are the least common and less than a dozen reports of multiple idiopathic aneurysms have been published. We present a case of an idiopathic, symptomatic renal artery aneurysm with fistulization to the renal vein and a concomitant abdominal aortic aneurysm in a 6-year-old boy. The diagnostic workup, surgical treatment, pathologic findings, and a review of the literature are presented.
