Extra-uterine (abdominal) full term foetus in a 15-day pregnant rabbit (original) (raw)

“…Studies in farmed or laboratory rabbits, for which dates of insemination are recorded, have facilitated accurate description of concurrent abdominal pregnancies and intrauterine fetuses of differing ages (13), suggesting that it is indeed feasible that the abdominal fetus described in this report originally arose during a previous pregnancy. This raises the question of whether the wild rabbit described here would have exhibited clinical signs associated with the presence of the lithopedion.…”

“…Abdominal pregnancies have been previously described in laboratory (8), pet (9–11), and farmed Oryctolagus cuniculus (1, 12, 13). Indeed, in farmed rabbits, use of artificial insemination has been postulated to be a factor in the pathogenesis of some cases (12).…”

“…Despite the few reports available, ectopic gestation has already been described in wild lagomorphs, farmed, laboratory, and pet rabbits. Nevertheless, few or no reproductive abnormalities were observed [20,[37][38][39][40][41].…”

“…According to the reports on this subject, the diagnosis is often based on the presence of palpable abdominal mass(es) and/or further discovery during the necropsy of at least one fetus that can be calcified (lithopedia) or not, still attached to an inflamed uterine horn with fibrosis by a thin fibrovascular stalk or to the abdominal surface by thread-like blood vessels [37,38]. Natural gestation and AG may occur simultaneously [39], as well as new pregnancies can coexist with dead fetuses from previous AG [20,38]. At least two studies have described the identification of fetuses of different gestational ages in pregnant rabbits [20,38].…”
