Severe methanol intoxication can cause widespread brain damage, including the putamen, caudate nuclei, and optic nerves. These MR and CT findings, confirmed by pathology, suggest a poor prognosis for affected patients.

Area of Science:

  • Neurology
  • Radiology
  • Toxicology

Background:

  • Methanol intoxication is a serious condition with potentially devastating neurological consequences.
  • Early and accurate diagnosis is crucial for patient management and prognosis.
  • Neuroimaging plays a vital role in identifying characteristic patterns of brain injury.

Observation:

  • This report details the magnetic resonance (MR) and computed tomography (CT) imaging findings in a patient with severe methanol intoxication.
  • Pathologic correlation was performed to confirm the observed radiological abnormalities.
  • The study highlights specific patterns of brain damage associated with methanol toxicity.

Findings:

  • The neuroimaging revealed bilateral hemorrhagic necrosis of the putamen and caudate nuclei.

  • Extensive subcortical necrosis was observed.
  • Symmetric bilateral necrosis of the pontine tegmentum and optic nerves was also identified.

    • Implications:

    • The observed pattern of brain injury, particularly the involvement of basal ganglia and optic nerves, is associated with a poor prognosis.
    • These findings emphasize the utility of MR and CT in diagnosing methanol intoxication and predicting outcomes.
    • Understanding these neuroimaging markers can aid clinicians in managing patients and counseling families.
