The authors report an unusual presentation of congenital mesoblastic nephroma as a multilocular cystic renal lesion. Prenatal sonography revealed a unilateral, encapsulated, multilocular cystic mass with solid components measuring 5.7 × 5.4 × 4.3 cm in the left renal fossa. There was no increase in vascularity and no signs of hydrops fetalis. On the forth postnatal day left-sided radical nephrectomy was performed and histopathological examination revealed cellular type congenital mesoblastic nephroma. A multicystic appearance is rare as the vast majority of prenatally diagnosed congenital mesoblastic nephroma cases presented in the literature are of the classic type with solid homogenous or heterogenous appearence.
作者报告了一例先天性中胚层肾瘤的罕见表现，其呈现为多房性囊性肾病变。产前超声检查显示，在左肾窝有一个单侧、有包膜的多房性囊性肿块，伴有实性成分，大小为5.7×5.4×4.3厘米。无血管增多，也无胎儿水肿迹象。出生后第4天进行了左侧根治性肾切除术，组织病理学检查显示为细胞型先天性中胚层肾瘤。多囊性外观较为罕见，因为文献中报道的绝大多数产前诊断的先天性中胚层肾瘤病例为经典型，表现为实性均匀或不均匀外观。
