Abstract

A 7-year-old Holstein cow, which had previously given birth to 3 normal calves, delivered a fullterm fetal monster (25kg). The monster showed the absence of the vertebral column caudal to the third thoracic vertebra and the spinal cord terminated in the vertebral arch of the first thoracic vertebra. The muscles supplied by nerve fibers from the spinal cord caudal to the thoracic segment suffered from atrophy. The head, neck and front limbs were externally normal. Atresia ani, malformations in the urogenital organs, and abnormality of the shape and ossification in the sternum were also seen. This case was regarded as Perosomus elumbis.
