Perosomus elumbis is a rare and singular vertebral dismorfism. Malformation or improper migration of the neural tube during the tail-bud stage, accompanied by partial agenesis of the caudal spinal cord, seems to be the cause of this abnormality. Its aetiology is still unknown. Only the reporting of further cases will permit to improve the knowledge of its origin. Therefore we invite bovine practitioners and breeders to submit all animals with such malformation to research or diagnostic centers.
