OBJECTIVE
To report a rare case of a kidney lesion, finally diagnosed as inflammatory pseudotumor, underwent partial nephrectomy and saved the kidney.
METHODS
Case report and experience sharing.
RESULTS
A 4-year-old boy expressed merely occasionally abdominal pain with space-occupying lesion of the right kidney that was indicative of renal malignant carcinoma. The boy underwent partial nephrectomy and perinephric lymph node dissection, and the mass was histopathologically diagnosed as IPT of renal parenchyma, accompanied with lymph nodes reactive hyperplasia. During the subsequent 20 months' follow-up, the child was all clinically very well, the residual right kidney regrew approximately to the same size as the left one by catch-up growth, remained normal glomerular filtration rate, and did not require additional therapy.
CONCLUSION
Among the affected organs of IPT, kidney is indeed of rare involvement, especially in children. Children has immeasurable potentiality for restoration and regeneration, IPT of the kidney should be given sufficient attention when confronted patients with renal mass lesion in the differential diagnosis, to avoid unnecessary surgical intervention.
目的
报告一例罕见的肾脏病变病例，最终诊断为炎性假瘤，行肾部分切除术并保留了肾脏。
方法
病例报告及经验分享。
结果
一名4岁男孩仅偶尔出现腹痛，右肾有占位性病变，提示肾恶性肿瘤。该男孩接受了肾部分切除术及肾周淋巴结清扫术，肿块经组织病理学诊断为肾实质炎性假瘤，伴有淋巴结反应性增生。在随后的20个月随访中，患儿临床情况良好，右侧残留肾脏通过追赶生长恢复至与左侧大致相同大小，肾小球滤过率保持正常，无需额外治疗。
结论
在炎性假瘤累及的器官中，肾脏确实很少受累，尤其是在儿童中。儿童具有不可估量的恢复和再生潜力，在鉴别诊断中遇到肾肿块病变患者时，应充分重视肾脏炎性假瘤，避免不必要的手术干预。
