Histological and histochemical observations on the muscular lesions in a newborn calf with hydranencephaly

Histological and histochemical examinations were carried out on the muscular lesions in a newborn calf with hydranencephaly. The muscular lesions were composed of the fascicles of atrophic muscular fibers histologically. Histochemical examination revealed that the groups of histochemically uniform muscular fibers (fiber-type grouping) were present in the lesions, suggesting that the muscular lesion of this case was a neurogenic disorder.
