A fifty-three-year-old woman was admitted for gross hematuria and left lumbago. She was diagnosed as having left renal arteriovenous malformation (AVM) by renal angiography, but contrast enhanced CT of her left kidney demonstrated a low density area of renal parenchyma adjacent to AVM. Because a renal tumor could not be denied completely, we performed translumbar nephrectomy. No renal tumor was found in the removed kidney, and she was diagnosed as having cirsoid type AVM of the left kidney. The low density area in contrast enhanced CT was suspected to be indicating the ischemic renal parenchyma due to the steal phenomenon of renal AVM. This is the first report of a renal AVM with ischemic renal parenchyma demonstrated by CT.
一名53岁女性因肉眼血尿和左侧腰痛入院。经肾血管造影诊断为左肾动静脉畸形(AVM),但左肾增强CT显示AVM附近肾实质有低密度区。由于不能完全排除肾肿瘤,我们进行了经腰肾切除术。切除的肾脏中未发现肾肿瘤,她被诊断为左肾蔓状型AVM。增强CT中的低密度区怀疑是由于肾AVM的盗血现象导致的肾实质缺血。这是首例通过CT显示肾实质缺血的肾AVM报告。
