Methadone overdose can cause rare brain imaging changes in the cerebellum and basal ganglia. This case highlights unusual FLAIR and DWI hyperintensities in these areas following intoxication.
Area of Science:
- Neuroimaging
- Toxicology
- Neurology
Background:
- Methadone is an opioid agonist used for pain management and opioid use disorder treatment.
- Intoxication can lead to central nervous system depression and various neurological complications.
- Cerebellar and basal ganglia involvement in methadone overdose is rarely reported.
Purpose of the Study:
- To report a rare case of methadone overdose with concurrent cerebellar and basal ganglia involvement.
- To describe the characteristic neuroimaging findings in this specific clinical presentation.
Main Methods:
- Case report of a 29-year-old male patient with methadone intoxication.
- Cerebral computed tomography (CT) scan.
- Brain magnetic resonance imaging (MRI) including FLAIR and Diffusion Weighted Imaging (DWI) sequences.
Main Results:
- Cerebral CT showed hypodense signals in the right cerebellar hemisphere.
- Brain MRI revealed FLAIR and DWI hyperintensities in both cerebellar hemispheres and basal ganglia (globi pallidi).
- These findings were consistent with methadone overdose.
Conclusions:
- This is the first reported case detailing both cerebellar and basal ganglia involvement in methadone overdose.
- Advanced MRI sequences like FLAIR and DWI are crucial for identifying these rare neurotoxic effects.
- Clinicians should consider methadone toxicity in patients presenting with coma and these specific brain imaging abnormalities.
