Foetus in foetu is a very unusual cause of abdominal mass in the infancy. Twenty cases only have been quoted in the literature. Two others cases are added, concerning two girls: a three months infant, second born from a genuine twin pregnancy, and a four weeks newborn whose the mass was discovered before the birth, on routine ultrasonography. In together, the diagnosis was made in operating room, then confirmed by pathologic studies. Literature data are recorded, and the difference between teratomas and foetus in foetu is point. The pathogeny remains obscure. It could result from the inclusion of a parasite twin in his bearer, become during embryologic stage of the delimitation.
胎中胎是婴儿期腹部肿块非常罕见的病因。文献中仅报道过20例。现补充另外两例，均为女孩：一例是三个月大的婴儿，系同卵双胎妊娠的次胎；另一例是四周大的新生儿，其肿块在出生前经常规超声检查发现。两例均在手术室确诊，随后经病理研究证实。记录文献数据，并指出畸胎瘤与胎中胎的区别。病因仍不明确。它可能是由于在胚胎发育阶段的分隔过程中，一个寄生性双胎被其宿主包入所致。
