    DSA: Diagnosis
     

    The angiogram shows the aneurysm arising from the branching point of the left main renal artery (MRA).

     
    Area of Interest: Vascular; Imaging Technique: Catheter arteriography; Procedure: Catheters; Special Focus: Aneurysms;

    The angiogram shows renal parenchymal vascularization arising from the upper branch of the aneurysm.
