Demyelination of the lateral geniculate nucleus in central pontine myelinolysis.

Postmortem examination of the central nervous system in 6 of 9 patients with central pontine myelinolysis (CPM) revealed demyelination in the lateral geniculate nucleus (LGN). Histologically, the geniculate lesions consisted of myelin swelling and disintegration, largely in the central part of the nucleus, with preservation of axons and neuronal perikarya. The pathological changes resembled those found in the basis pontis in CPM.
