Inflammatory pseudotumor (IPT) of the kidney is a rare benign disorder with unknown etiology. In IPT patients, some nonspecific symptoms might present, such as fever, hematuria, and back pain. As it can appear on computed tomography and magnetic resonance imaging as a hypovascular mass with surrounding fat stranding, IPT can be misdiagnosed as a primary tumor. Since the clinical symptoms, radiographic features, and preoperative findings can be inconsistent, it is imperative to confirm IPT based on histopathological assessment. In the present study, we describe a case of renal IPT in a 13-year-old girl. The patient was treated with nephrectomy of the right kidney since the preoperative diagnosis was renal carcinoma. Pathological examination revealed an IPT. This article emphasizes the importance of preoperative definitive diagnosis in avoiding unnecessary nephrectomy.
肾脏炎性假瘤（IPT）是一种罕见的良性疾病，病因不明。在 IPT 患者中，可能会出现一些非特异性症状，如发热、血尿和腰痛。由于其在计算机断层扫描和磁共振成像上表现为低血管性肿块伴周围脂肪条纹，因此可能被误诊为原发性肿瘤。由于临床症状、影像学特征和术前发现可能不一致，因此基于组织病理学评估来明确诊断 IPT 至关重要。本研究描述了一例 13 岁女孩的右肾 IPT。由于术前诊断为肾癌，患者接受了右肾切除术。病理检查显示为 IPT。本文强调了术前明确诊断的重要性，以避免不必要的肾切除术。
