摘　　要：目的认识儿童非霍奇金淋巴瘤(NHL)肾脏浸润的各种MRI表现。方法分析11例经病理证实的儿童NHL肾脏浸润的MRI表现特征,讨论其鉴别诊断;并参照同时行MRI检查的儿童淋巴瘤总例数对其肾脏浸润阳性率进行分析。结果11例儿童NHL肾脏浸润表现为单侧单结节型1例;双侧多结节型8例;单侧单结节伴双侧肾脏弥漫浸润型1例;双侧肾皮质弥漫性增厚而无明显结节1例。11例均有不同程度的腹腔多脏器侵犯。NHL病灶于T1加权像可为低或略高信号,于T2加权像上均为均匀低信号,无中央坏死区。结论儿童NHL肾脏浸润的MRI表现具有特征性,MRI能比较准确显示肾脏浸润的情况,对临床分期及疗效观察有重要价值。Objective To understand the various MRI manife stations of renal involvement of non Hodgkin' s lymphoma (NHL)in children.Methods MRI findings and characteristics in11cases confirmed by pathology with NHL renal involvement were retr ospectively analyzed and the differential diagnosis was discussed.The positive rates of renal involvement in all lym phomas in children were also investi gated.Results In 11cases NHL,1case had single mass in one kidney;8cases showed multiple nodulesr in b oth kidneys;1case which the two kidneys were widespread gradually had only s ingle mass in one kidney;1case which the kidneys' cortex penetrated in-crassation had no typical mass.All c ases had encroached on abdominal vis cera in various degrees.All focuses showed low or gently high signal on T 1 WI and low signal on T 2 WI,which had no putrescence in the ce nter section.Conclusion The MRI signs of renal involvement of NHL in children have certain characteristics.It is accurate to display the renal involv ement of NHL by MRI scan.MRI is very valuable for the clinical staging and for the evaluation of therapeutic effects in NHL.[
