Fibromuscular dysplasia is an abnormal cell growth of the arterial wall that usually affects the renal and carotid arteries. It may lead to stenosis, tortuosity, aneurysm, or dissection of the artery and can potentially compromise circulation, resulting in total occlusion and infarction of the recipient area. We report a case of a young male who presented with severe acute abdominal pain on the right side, associated with nausea, vomiting, and constipation. Computed tomography of the abdomen with intravenous contrast revealed an acute renal infarction in a focal area at the lower pole of the right kidney. Subsequent computed angiography showed dissection of a segmental branch of the right renal artery associated with fibromuscular dysplasia and a beading appearance of the right renal artery. Both the renal function test and urinalysis were normal. The patient was treated with an unfractionated heparin infusion, leading to the resolution of his abdominal pain. He was subsequently discharged home uneventfully on oral aspirin.
