A 52-year-old African-American woman with a history of Ehlers‐Danlos type IV syndrome presented with chest and abdominal discomfort. A CT angiogram of the chest and abdomen was performed which revealed renal artery aneurysms. Panel A: the arrows point to the location of the renal artery aneurysms. (Image obtained using CT angiogram and post-processed using the volume rendering technique.) Panel B: the arrow points to a part of the right renal artery aneurysm that lacks contrast enhancement, which suggests thrombus formation. The arrowhead points to the left renal artery aneurysm that has contrast enhancement, which suggests flow. The ring enhancement around the renal artery aneurysms suggests calcium deposition. (Image obtained using CT angiogram.) Panel C: the thin arrow points to an area without contrast enhancement, which suggests thrombus formation. The arrowhead points to the aorta at the level of the renal arteries.The thick arrow points to an area of the aneurysm with contrast enhancement, which suggests flow. (Image obtained using CT angiogram and post-processed using the maximal-intensity-projection technique.) Owing to the spontaneous resolution of her symptoms and the complicated nature of Ehlers‐Danlos type IV syndrome, she was treated conservatively with medications.
