Some even go so far as to include with spina bifida occulta conditions in which the anomaly is not in the bony structures, but presumably in the spinal cord itself. On purely clinical grounds, Fuchs2 has described such conditions as myelodysplasia. He considers spina bifida occulta as the most severe form or stage of what he terms myelodysplasia. Few cases of the latter are mentioned in the literature. Spiller3 recently
