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.
