Fetus in fetu is an extremely uncommon cause of an abdominal mass in the neonate; fewer than 30 generally accepted cases are recorded in the literature. We report a case of intraabdominal fetus in fetu, with a unique location within an undescended left testicle. Chromosomal studies of cells from the fetus in fetu and the surviving infant revealed identical 46,XY karyotypes.
胎内胎是新生儿腹部肿块极为罕见的病因；文献中记载的公认病例少于30例。我们报告一例腹内胎内胎病例，其位于左侧未降睾丸内，位置独特。对胎内胎和存活婴儿的细胞进行染色体研究，结果显示二者的核型均为46,XY，完全相同。
