Ten days following the birth of five apparently normal pups, a female hamster developed bilateral abdominal distention. Both dam and pups appeared healthy at this time. The dam was killed, and postmortem examination revealed five additional pups encapsulated in the abdominal cavity outside the uterus. It was not possible to determine if this was a primary ectopic implantation or occurred secondary to the recent partuition.
在五只看似正常的幼崽出生十天后，一只雌性仓鼠出现双侧腹部膨胀。此时母鼠和幼崽看起来都很健康。母鼠被处死，尸检发现腹腔内子宫外还有五只幼崽被包裹着。无法确定这是原发性异位着床还是近期分娩继发的情况。
