Examination of a retroperitoneal fetus in fetu, diagnosed preoperatively, revealed previously unreported histologic findings in the vascular pedicle and membranous capsule that indicated that these structures are not "umbilical cord" or "amnion." These findings include nervous innervation of both structures and a well-defined lamina elastica interna and vaso vasorum in the artery of the vascular pedicle. Thus, strong support is provided for the theory that many examples of fetus in fetu are remarkably complex, well differentiated, highly organized teratomas. Additional arguments that favor the identity of fetus in fetu and teratoma are presented.
对术前诊断的腹膜后胎内胎进行检查，发现血管蒂和膜性囊中有先前未报告的组织学发现，表明这些结构并非“脐带”或“羊膜”。这些发现包括这两个结构的神经支配，以及血管蒂动脉中明确的内弹性膜和血管滋养管。因此，有力支持了这样一种理论，即许多胎内胎的例子是非常复杂、分化良好、高度组织化的畸胎瘤。还提出了支持胎内胎与畸胎瘤同一性的其他论据。
