Abstract

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.

摘要

在一头日本黑牛犊中发现了一例双头畸形、阿诺德-奇亚里畸形（ACM）和脊柱裂的病例。两个大脑和颅骨均表现出与患有ACM的单头病例相同的异常，且互为镜像。常见的表现为脑延长、小脑尾侧移位和发育不全、颅骨的背腹侧受压、扁平颅底以及枕骨大孔扩大。在我们的病例中还发现了颅骨腔隙。
