Two calves with unusual malformations of the skull and brain are described. Both calves showed doming of the posterior skull due to enlargement of the posterior fossa and cyst-like dilatation of the fourth ventricle. The cystic dilatation of the fourth ventricle formed a meningocoele in one calf. Aplasia of the cerebellar vermis was present in both calves. One calf showed agenesis of the corpus callosum. These features are consistent with the Dandy-Walker malformation of man.
描述了两头患有颅骨和脑部异常畸形的小牛。两头小牛均因后颅窝扩大和第四脑室呈囊肿样扩张而出现后颅骨穹隆。第四脑室的囊肿样扩张在一头小牛中形成了脑脊膜膨出。两头小牛均存在小脑蚓部发育不全。一头小牛表现为胼胝体发育不全。这些特征与人的丹迪-沃克畸形相符。
