    Summary
    This summary is machine-generated.

    Marchiafava-Bignami disease, a rare neurological condition, was diagnosed postmortem in a North American man with excessive white port wine consumption. This case highlights the disease in non-Italian populations and its specific lesion patterns.

    Area of Science:

    • Neurology
    • Neuroscience
    • Toxicology

    Background:

    • Marchiafava-Bignami disease (MBD) is a rare neurological disorder typically associated with chronic alcoholism.
    • Historically, MBD has been predominantly reported in individuals of Italian descent, often linked to the consumption of red wine.

    Observation:

    • A postmortem diagnosis of MBD was made in a 39-year-old North American male with no Italian ancestry.
    • The patient exhibited a history of excessive white port wine consumption.
    • Neuropathological examination revealed characteristic demyelination and necrosis primarily affecting the corpus callosum and hippocampal commissure.

    Findings:

    • The observed MBD lesion pattern spared the anterior commissure, middle cerebellar peduncles, optic chiasm, and centrum semiovale.

  • Concurrent Wernicke-Korsakoff encephalopathy and pellagroid neuronal changes were noted, suggesting broader nutritional deficiencies or toxic effects.
  • This case represents the fifth report of MBD in a native North American individual without Italian heritage.

    • Implications:

    • The findings challenge the historical association of MBD with specific ethnicities and red wine consumption.
    • This case underscores the importance of considering MBD in alcoholic patients presenting with specific neurological deficits, regardless of ancestry or specific beverage preference.
    • Further research into the pathogenesis of MBD and its varied clinical presentations is warranted.
