Acute renal infarction and acute pyelonephritis can have identical clinical presentations. Most of the computed tomography findings seen in acute renal infarction are similar to those in acute pyelonephritis, except for the characteristic cortical rim sign seen in acute infarction. This finding differentiates these two disorders. This sign may be subtle and not appreciated unless searched for diligently with appropriate computed tomography imaging at varying window settings with particular attention to the subcapsular region.
急性肾梗死和急性肾盂肾炎可具有相同的临床表现。急性肾梗死的大多数计算机断层扫描（CT）表现与急性肾盂肾炎相似，除了急性梗死中可见的特征性皮质边缘征。这一发现可区分这两种疾病。该征象可能很细微，除非在不同窗宽设置下通过适当的CT成像仔细寻找，尤其注意肾包膜下区域，否则可能无法识别。
