一名47歲的婦女主訴血尿和左側背痛至醫院求診。患者否認有最近的創傷、腎臟手術或者尿道疾病的病史。在64排多切面電腦斷層執行動脈相電腦斷層並使用製造商提供的工作站做出三維電腦斷層血管影像。在動脈相64排多切面電腦斷層與重組的電腦斷層血管影像發現左腎緊鄰著泌尿收集系統，在動脈分支與靜脈之間有彎曲的血管。依據電腦斷層影像的結果而做出曲張性腎臟動靜脈畸形的診斷。這名患者接受了傳統血管攝影檢查及經導管動脈栓塞治療腎臟動靜脈畸形。她在後續3個月的臨床追蹤中，依然沒有症狀。

A 47-year-old woman presented to our hospital with chief complaints of hematuria and left flank pain. The patient denied any recent history of trauma, renal surgery or urinary tract disease. Arterial-phase CT and three-dimensional CT angiography were performed by 64-row multiple detector computed tomography (64-MDCT) and manufacturer-provided workstation. Tortuous fistulas close to the collecting system between the branches of left renal artery and vein were found on arterial phase 64-MDCT and CT angiography. The diagnosis of cirsoid renal arteriovenous malformation (AVM) was made according to CT imaging findings. The patient underwent conventional angiography and transcatheter arterial embolization for renal AVM. She remained symptom free at three-month clinical follow-up.
