Acute alcohol intoxication presenting acquired lesion of the corpus callosum in a young healthy woman: A case of possible Marchiafava-Bignami disease

Background: Marchiafava-Bignami disease is a rare neurological disease characterized by acquired lesions of the corpus callosum. Although the major causative etiology is chronic alcoholism, a case caused by acute alcohol intoxication has not yet been reported.

Case presentation: A 19-year-old female with no known medical history or a history of chronic alcohol consumption was brought to the emergency department in a coma after binge alcohol consumption. Even after an overnight observation, she remained comatose. After a thorough examination including magnetic resonance imaging, which showed lesions of the corpus callosum, she was treated with thiamine for Marchiafava-Bignami disease. She recovered completely and at the follow-up, the callosum lesion had resolved.

Conclusion: This is a rare case within the spectrum of Marchiafava-Bignami disease caused by acute consumption of alcohol. Clinicians should be aware of this potentially devastating critical condition among patients with severe alcohol intoxication, which might have been overlooked.
