Renal infarction caused by fibromuscular dysplasia

Abstract

Introduction: Fibromuscular dysplasia (FMD) is an atherosclerotic/non-inflammatory disease, usually involving the renal and internal carotid arteries. Renal infarction is a rare condition that can present with flank pain and can be caused by FMD. Case Report: A 49-year-old female patient was admitted to the emergency department with complaints of flank pain, fever, nausea, vomiting, and chills. Her blood pressure was normal. Abdominal examination showed right costovertebral tenderness. Laboratory assessment showed hematuria, leukocytosis, increased C-reactive protein (CRP), and increased lactate dehydrogenase (LDH). Nephrolithiasis was strongly considered a cause of pain because of the nature of the pain and the presence of hematuria. The urinary system ultrasound was normal. On the computed tomography (CT), in contrastenhanced sections, an infarct area was detected in the lower pole of the right kidney. In renal angiography, severe focal stenosis was seen in the polar renal artery, and angioplasty was made. Conclusion: Renal infarction can be caused by FMD and may be misdiagnosed as renal colic.
