Fibromuscular Dysplasia Presenting as a Renal Infarct

Fibromuscular dysplasia (FMD) is a condition caused by an abnormal development or growth of cells in the arterial walls in the body. We present a case of a 49-year-old male who came in with a sudden onset of severe left-sided abdominal pain. Computed tomography (CT) scan of the abdomen was suggestive of a left renal infarct. He underwent renal angiography that showed FMD and a clot located in the anterior branch of the left renal artery. The patient was then treated with apixaban for the clot and amlodipine for the associated hypertension. Our case will highlight the importance of recognizing renal infarction as an initial presentation of FMD.
