Renal infarction secondary to fibrous dysplasia and aneurysm formation of renal artery.

We report a case of a previously healthy forty-year-old man with bilateral renal artery stenosis secondary to bilateral medial fibrous dysplasia. He was additionally found to have a dissecting aneurysm of the left upper renal artery branch with resultant infarction of the upper and middle pole renal segments. We believe renal infarction secondary to medial fibrous dysplasia with occlusion of the renal artery associated with a dissecting aneurysm has not been reported, and we report the first such case. A multimodality treatment approach was utilized.
