Spongy degeneration of the CNS: an instance of the rare juvenile form.

To our knowledge, the juvenile form of spongy degeneration of the CNS (SD-CNS); van Bogaert-Bertrand disease) has been described previously only three times. We report the case of 21 1/4-year-old Japanese woman who was first seen at the age of 11 with growth retardation, ptosis, and ophthalmoplegia. Her progressive neurodegenerative disease included retinitis pigmentosa, blindness, partial deafness, cerebellar dysfunction, hyporeflexia, and muscle wasting. Simultaneous endocrine defects were diabetes mellitus and probable hyperaldosteronism. Heart block developed later. She died of bronchopneumonia. Autopsy showed CNS stigmas typical of spongy degeneration. Additional findings included peripheral nerve demyelination, neurogenic muscle atrophy, pituitary and pancreatic atrophy, right adrenal agenesis, and a left adrenal coritcal lipid-cell adenoma. To our knowledge, our patient was the oldest survivor, the first patient of Japanese ancestry, and had a unique concurrence of certain oculoendocrine defects.
