A stillborn bovine male fetus with abdominal distention, arthrogryposis and atresia ani was presented for diagnostic evaluation. At necropsy, this fetus had a large amount of ascites, urachal obstruction and marked bladder distention. The ventral surface of the bladder had ruptured and attached to the abdominal wall by fibrinous adhesions. There was bilateral hydronephrosis with moderate pelvic dilatation and cortical attenuation. The rectum was filled with meconium but the anus was imperforate. The right forelimb was contracted. The cause(s) of these abnormalities could not be determined; however, we believe that developmental abnormalities during embryogenesis may be the result of chromosomal abnormalities.
一头死产的雄性牛胎儿，有腹胀、关节弯曲和肛门闭锁，被送来做诊断评估。尸检时，该胎儿有大量腹水、脐尿管梗阻和明显的膀胱扩张。膀胱腹面破裂，通过纤维性粘连附着于腹壁。有双侧肾积水，肾盂中度扩张，肾皮质变薄。直肠充满胎粪，但肛门闭锁。右前肢挛缩。这些异常的原因无法确定；然而，我们认为胚胎发育过程中的发育异常可能是染色体异常的结果。
