title: Anomalous development of the spinal cord in a calf.
abstract: A full term Friesian bull calf was born unable to stand. The dam had no signs of illness during pregnancy. In the thoracic spinal cord there was anomalous development of the central canal and a dorsally placed fusiform and longitudinal dilatation. Mild inflammatory lesions were seen in some body organs and central nervous system where they were suggestive of viral infection. Several skeletal muscles had an extended range of muscle cell cross sectional areas and some cells had numerous internal nuclei.
