[Case of splenogonadal fusion with genital malformation].

A case of splenogonadal fusion associated with a posterior hypospadias is presented. The testis was ectopic, leading to realize an arteriography. The vascularization of the splenogonadal fusion was on the dependance of the renal artery. The testis and splenic tissues were separated, with anastomosis between the spermatic vessels and the epigastric one; this anastomosis was unsuccessful. Eighty nine examples of splenogonadal fusion have been reported. They are divided into two forms: the continuous type is often associated with other malformations (limb, micrognathia). These associations are explained by the embryology. The treatment must be conservative.
