ABSTRACT

 

Ashareyoun H, Ragh MJ, Ghodrati MS, Vali Y, Reisdanaei MA., Radiography of Perosomus elumbis in sheep, Onl J Vet Res., 21(6):323-327, 2017.    Skeletal Malformation Syndrome in sheep is rarely described. Perosomus elumbis (PE) is a lethal congenital defect characterized by absence or agenesis of caudal spine and cord with associated musculoskeletal malformation of hind quarters. A 3.2kg male lamb was delivered normally at 150d of a 2nd gestation, but could not, stand. Physical examination, hind limb dysplasia and radiography confirmed PE. Pelvic bones and femur appeared hypoplastic asymmetric with atrophy of hind limb muscles. Lumbar, sacral and coccygeal vertebrae were absent. Pathogenesis of PE is unknown, but genetic factors and/or exposure to  teratogenic agents during embryogenesis are suspected. Images are shown in support of findings.

 

Key Words: Perosomus elumbis, Radiography, Sheep.
