Pathologic features include prominent demyelination in the central PONS with sparing of axons and neurons. This condition is usually associated with systemic disorders such as HYPONATREMIA; chronic ALCOHOLISM; LIVER FAILURE; severe BURNS; malignant NEOPLASMS; hemorrhagic PANCREATITIS; HEMODIALYSIS; and SEPSIS. The rapid medical correction of hyponatremia has been cited as a cause of this condition. 341.8 is a specific code that can be used to specify a diagnosis 341.8 contains 11 index entries View the ICD-9-CM Volume 1 341.* hierarchy Alternate Terminology Central demyelination of corpus callosum Central pontine myelinosis Marchiafava (-Bignami) disease  Index entries containing 341.8: Demyelination, demyelinization central nervous system 341.9 specified NEC 341.8 corpus callosum (central) 341.8 Disease, diseased - see also Syndrome demyelinating, demyelinizating (brain stem) (central nervous system) 341.9 specified NEC 341.8 Marchiafava (-Bignami) 341.8 spine, spinal 733.90 demyelinating NEC 341.8 Encephalopathy (acute) 348.30 demyelinating (callosal) 341.8 infantile cystic necrotizing (congenital) 341.8 Marchiafava (-Bignami) disease or syndrome 341.8 Myelinosis, central pontine 341.8 Neuromyelitis 341.8 ascending 357.0 optica 341.0 Syndrome - see also Disease Marchiafava-Bignami 341.8
