Abstract:
This is a case of a 65-year-old woman with a history of coronary artery disease, who presented with hypertension that was poorly controlled by medical treatment. A rotational abdominal aortogram was done, followed by selective right and left renal artery angiograms. Imaging of renal artery aneurysms can be tricky, and some aneurysms might be misdiagnosed for a tortuous renal artery. In such cases, the physician needs to maintain a high index of suspicion towards this condition. Three-dimensional reconstruction allows for a better visualization of the aneurysm and its surrounding structures. It also guides the operator to the projection that best reveals the anatomical criteria of the aneurysm.
