Insights
A toddler presented in a coma due to a fentanyl patch, showing rare brain MRI changes. Despite the severity, she had a good neurologic outcome, highlighting thorough examination importance.
Area of Science:
- Pediatric Neurology
- Toxicology
- Emergency Medicine
Background:
- Altered mental status in children presenting to the emergency department necessitates a broad differential diagnosis.
- Opioid intoxication is a critical consideration in pediatric cases of altered mental status.
- Prompt diagnosis and management are crucial for improving outcomes in pediatric poisoning.
Observation:
- A 19-month-old female presented with coma and a fentanyl patch discovered adhered to her back.
- Brain magnetic resonance imaging revealed changes consistent with toxic spongiform leukoencephalopathy.
- The patient experienced a good neurologic recovery despite the severe presentation.
Findings:
- Fentanyl intoxication can lead to toxic spongiform leukoencephalopathy, a rare but serious condition.
- The case demonstrates an unusual MRI finding in opioid toxicity.
- Despite typically poor prognoses, good neurologic outcomes are possible with prompt intervention.
Implications:
- This case underscores the critical importance of a comprehensive physical examination in diagnosing pediatric coma.
- It highlights a rare MRI finding associated with opioid intoxication, expanding the understanding of its neurological effects.
- Physicians should consider opioid exposure in the differential diagnosis of pediatric altered mental status, even with unusual presentations.
Abstract:
Children with altered mental status who present to the emergency department have a broad differential diagnosis. We report a case of a 19-month-old girl who presented in coma and who was later found to have a fentanyl patch adhered to her back. She was found to have changes on brain magnetic resonance imaging consistent with a toxic spongiform leukoencephalopathy but had a good neurologic outcome. This case report illustrates the importance of a thorough physical examination in children in coma and a rarely reported magnetic resonance imaging finding that has been seen in opioid intoxication and is usually associated with severe morbidity and mortality.
