Central nervous system and vertebral malformation resembling the Arnold-Chiari syndrome in a Simmental calf.

摘要

Multiple congenital anomalies were identified in a stillborn calf, including severe cerebellar hypoplasia and central nervous system abnormalities resembling the Arnold-Chiari syndrome of malformation of calves. The Arnold-Chiari malformation occurs sporadically and has little economic impact, whereas cerebellar hypoplasia implies the presence of BVD virus in the herd.
