Cerebellar hypoplasia associated with Arnold-Chiari malformation in a Japanese shorthorn calf.
A case of Arnold-Chiari malformation associated with severe cerebellar hypoplasia in a Japanese Shorthorn calf is reported. Histological examination revealed severe and extensive lesions in the cerebellar vermis. Hypoplasia of the cerebellum in Arnold-Chiari malformation appeared to indicate the abnormal embryonic development of the neural tissue, but the exact cause is not known.
