The renal artery aneurysm (RAA) is defined as a renal artery segment that is twofold dilated than normally. It is very rare in children and often asymptomatic. However, it can cause severe hypertension (HTN) and kidney failure. Herein, we report a 14-year-old boy who with RAA which was presented with back pain. His medical history was remarkable for essential HTN that was refractory to antihypertensive medications. Plain abdominal radiography revealed calcification at the right flank area. On computed tomography images, calcification surrounding the right renal artery was detected. Selective renal angiography showed totally occluded right renal artery segment. Calcified RAA was detected on the operation and removed. Two months after, blood pressure was under control, but there was no functioning right kidney on DMSA. We think that clinicians should keep in mind RAA in the differential diagnosis of treatment-resistant HTN and use other radiologic methods even if Doppler is normal.
肾动脉动脉瘤（RAA）定义为比正常情况下扩张两倍的肾动脉节段。它在儿童中非常罕见，通常无症状。然而，它会导致严重的高血压（HTN）和肾功能衰竭。在此，我们报告了一例 14 岁男孩，他因 RAA 引起腰痛。他的病史为难治性 HTN，对降压药物无反应。腹部平片显示右侧腰部有钙化。在 CT 图像上，检测到右肾动脉周围的钙化。选择性肾血管造影显示右肾动脉节段完全闭塞。在手术中发现并切除了钙化的 RAA。两个月后，血压得到控制，但 DMSA 上无功能的右肾。我们认为，临床医生在治疗抵抗性 HTN 的鉴别诊断中应牢记 RAA，并在即使多普勒正常的情况下也使用其他影像学方法。
