We describe a pediatric patient with upper tract collecting system dilatation caused by a periureteric venous ring. The diagnosis was made after MR urography. This rare inferior vena caval anomaly has not been documented in the pediatric literature, nor have the MRI appearances been described. MRI is ideally suited for the assessment of suspected retrocaval ureters in order to identify this variant so that an appropriate surgical approach can be planned.
我们描述了一名患有由输尿管周围静脉环引起的上尿路集合系统扩张的儿科患者。诊断是在磁共振尿路造影后做出的。这种罕见的下腔静脉异常在儿科文献中尚未有记载，其MRI表现也未被描述过。MRI非常适合评估疑似腔静脉后输尿管，以识别这种变异，从而能够规划合适的手术方法。
