We discuss 5 children with simple renal cysts, 2 of whom were diagnosed initially as having a Wilms tumor or mesoblastic nephroma. The most common presenting feature of this lesion is a palpable mass, especially in the infant or younger child. In older children characteristic radiographic features can suggest a correct preoperative diagnosis. However, distinguishing a simple cyst and a solid tumor with necrotic degeneration may not be possible in the infant and younger child, and surgical exploration is indicated.
我们讨论了5例单纯性肾囊肿患儿，其中2例最初被诊断为肾母细胞瘤或中胚叶肾瘤。该病变最常见的表现特征是可触及肿块，尤其是在婴儿或年幼儿童中。在年龄较大的儿童中，特征性的影像学表现有助于术前做出正确诊断。然而，在婴儿和年幼儿童中，可能无法区分单纯囊肿和伴有坏死退变的实体瘤，此时需进行手术探查。
