Eight animals with abdominal fetuses were found in a relatively small colony of Djungarian hamsters. All the fetuses were macerated. Some had remains of an amniotic sac with an umbilical attachment to a placenta adherent to the peritoneum, but others were without placental remains. Gross and histological examinations failed to reveal any ruptures of the uterus or oviducts. It was not possible to decide whether the abdominal pregnancies were primary or secondary.
在一个相对较小的黑线毛足鼠群体中发现了8只怀有腹腔胎儿的动物。所有胎儿均已浸软。有些胎儿有羊膜囊遗迹，脐带附着于贴附在腹膜上的胎盘，但其他胎儿没有胎盘遗迹。大体和组织学检查均未发现子宫或输卵管有任何破裂。无法确定腹腔妊娠是原发性还是继发性的。
