We report an instance of splenic heterotopia arising within the left kidney of an otherwise normal female infant. Embryologic considerations suggest that fusion of nephrogenic mesoderm and splenic anlage in the second month of gestation accounts for the observed findings. Although splenic-mesonephric (splenogonadal) fusion is a well-characterized, although rare, malformation, we were unable to find any previous description of splenic-metanephric fusion.
我们报告了一例脾脏异位于一名正常女婴左肾内的病例。胚胎学方面的考虑表明，妊娠第二个月时肾源性中胚层与脾原基的融合是所观察到的结果的原因。尽管脾-中肾（脾性腺）融合是一种特征明确但罕见的畸形，但我们未能找到之前关于脾-后肾融合的任何描述。
