Mesoblastic nephroma is a rare renal tumour mainly observed in neonates and young infants. The authors report a case in a 5-day-old new-born infant presenting with an isolated abdominal mass occupying the left hypochondrium and flank. Ultrasonography demonstrated a 4 cm heterogeneous mass in the lower pole and middle of the left kidney. CT showed an intensely contrast-enhanced heterogeneous mass. The patient was treated by left radical nephrectomy with an uneventful postoperative course. The outcome was favourable without recurrence with a follow-up of one year. Mesoblastic nephroma is considered to be a benign tumour. The diagnosis is suggested by clinical, ultrasonographic and CT findings. Treatment is based on radical nephrectomy. In the light of this case, the authors discuss the clinical, radiological and therapeutic aspects of this tumour.
中胚叶肾瘤是一种罕见的肾脏肿瘤，主要见于新生儿和婴幼儿。作者报告了一例5日龄新生儿病例，该患儿表现为孤立性腹部肿块，占据左季肋部和侧腹部。超声检查显示左肾下极和中部有一个4厘米的不均匀肿块。CT显示一个强化明显的不均匀肿块。患者接受了左肾根治性切除术，术后过程顺利。随访一年，结果良好，无复发。中胚叶肾瘤被认为是一种良性肿瘤。根据临床、超声和CT表现可作出诊断。治疗以肾根治性切除术为基础。鉴于此病例，作者讨论了该肿瘤的临床、放射学和治疗方面。
