Fatal fentanyl-associated cerebellitis in a young man

Area of Science:

• Neurology
• Toxicology
• Infectious Diseases

Background:

• Opioid overdose is a common emergency presenting with coma and respiratory failure.
• Naloxone is the standard treatment for opioid overdose.
• Cerebellitis, inflammation of the cerebellum, is a rare neurological complication.

Observation:

• A 22-year-old male presented with coma and respiratory failure, initially suspected as opioid overdose.
• The patient did not respond to naloxone, prompting further investigation.
• Head CT revealed cerebellitis, leading to obstructive hydrocephalus and herniation.

Findings:

• Cerebellitis, a rare complication of opioid use, can present with severe neurological deficits.
• The patient's condition deteriorated despite intensive neurosurgical and ICU interventions.
• This case underscores the potential for severe neurological sequelae from opioid toxicity.

Implications:

• Cerebellitis should be considered in patients with unexplained coma and respiratory failure, especially with a history of opioid use.
• The evolving opioid and fentanyl epidemic may lead to an increase in rare complications like opioid-induced cerebellitis.
• Further research is needed to understand the pathophysiology and management of this rare complication.
