The case of a 13-month-old boy with fibromuscular dysplasia (FMD) presenting with a large saccular aneurysm of the left renal artery and renovascular hypertension is reported. Renal and intrarenal arteries showed numerous small aneurysms alternating with stenoses. All arterial lesions were localized to the left kidney. After left nephrectomy, the patient's blood pressure normalized. Histopathologic examination of the arteries disclosed changes typical of medial fibroplasias, the most frequently described form of FMD in children. This diagnosis is rewarding as it represents a surgically curable cause of severe hypertension.

    The most common pathogenetic lesion associated with renovascular hypertension is atherosclerosis. Next in etiologic incidence is arterial fibromuscular hyperplasia. The only other lesion common enough to warrant percentage classification is renal artery aneurysm. Here, we present a case with an...

    A 53-year-old woman presented with flank pain and hematuria. She was suspected of having a renal stone but instead was found to have a segmental renal infarction. Further evaluation revealed an atrial septal aneurysm, which was presumed to be the source of an embolism. Renal emboli should be...

    A case of giant renal artery aneurysm in a 63-year-old man is presented. Renal artery aneurysms are rare (incidence of <1%) and this case is one of the largest giant renal artery aneurysms recorded in the literature. This case also demonstrates the value of multidetector spiral CT renal...

    The article presents a case study on the endovascular treatment of renal artery aneurysm (RAA). Some criteria for repair are: symptomatic lesions, RAA with distal emoliation, and patients with one kidney. Traditional treatment of RAA is through aneurysmectomy and renal artery reconstruction or...
