Spontaneous Renal Artery Dissection with Renal Infarct

A 51-years-old woman was admitted to emergency service with left flank pain and nausea for the last few hours. She denied history of the renal stone disease. Abdominal examination revealed tenderness of left flank region. Vital signs were insignificant. Microscopic haematuria was observed on the urine analysis. Leucocyte count was 9530/mm3. Total triglyceride and cholesterol levels were high than normal values. The abdominal US was normal. Contrast-enhanced abdominal computed tomography (CT) revealed irregular and long segment stenotic left renal artery due to spontaneous dissection and wedge-shaped infarcts at the lower pole of the left kidney (Figure 1). 3D volume rendering reformatted CT image revealed a disconnected focal area on the left renal artery due to dissection (stippled red arrow). The proximal segment of the left renal artery (yellow arrow) were normal on the reformatted images (Figure 2). The patient subsequently underwent endovascular treatment. The patient was discharged on the 3rd day after treatment with no further symptoms or complications. The patient’s consent was assessed.
