Excessive proliferation of the peripelvic fat of the kidney (EPPF) is a benign process with an innocuous effect on the patient. However, this condition may assume major clinical significance by producing pyelocalyceal deformities that may be mistaken for true renal masses. Rarely, EPPF may masquerade as a renal pelvic tumor. We present the second reported case of EPPF simulating a renal pelvic tumor and review the history as well as the characteristic radiographic and sonographic features of this condition.
肾窦周围脂肪过多增生（EPPF）是一种良性病变，对患者影响不大。然而，这种情况可能具有重要的临床意义，因为它会导致肾盂肾盏畸形，可能被误诊为真正的肾脏肿块。EPPF很少会伪装成肾盂肿瘤。我们报告了第二例EPPF模拟肾盂肿瘤的病例，并回顾了该疾病的病史以及特征性的影像学和超声特征。
