Dicephalus, Arnold-Chiari malformation and spina bifida in a Japanese black calf.
A case of dicephalus, Arnold-Chiari malformation (ACM) and spina bifida was reported in a Japanese Black calf. Both brains and crania showed the same abnormalities as those of the monocephalic cases with ACM and were mirror-images of each other. The common findings were elongation of the brain, caudal displacement and hypoplasia of the cerebellum, dorso-ventral compression of the skull, platybasia, and enlargement of the foramen magnum. The craniolacunia was also found in our case.
