Background:
Manganese encephalopathy is a potential complication of parenteral nutrition. Lack of early recognition leads to unnecessary testing and to continued exposure to manganese.
Methods:
Case report and review of the literature.
Results:
We describe the clinical and imaging findings of a patient with manganese encephalopathy in whom the diagnosis was delayed due to lack of recognition of the characteristic imaging findings.
Conclusion:
Manganese encephalopathy has protean clinical and imaging findings that can easily be overlooked.
Insights
Manganese encephalopathy, a complication of parenteral nutrition, is often missed. Early recognition of its diverse clinical and imaging signs is crucial to prevent prolonged manganese exposure and unnecessary tests.
Area of Science:
- Neurology
- Toxicology
- Radiology
Background:
- Manganese encephalopathy is a neurological disorder.
- It can arise as a complication of parenteral nutrition.
- Delayed diagnosis leads to further manganese exposure and extensive medical workups.
Observation:
- A case report details a patient with manganese encephalopathy.
- The patient's diagnosis was delayed due to unrecognized characteristic imaging findings.
- This highlights the challenge in identifying the condition.
Findings:
- Manganese encephalopathy presents with varied clinical symptoms.
- Characteristic neuroimaging findings are often overlooked.
- The protean nature of the findings contributes to diagnostic delays.
Implications:
- Emphasizes the need for increased awareness among clinicians.
- Highlights the importance of recognizing specific imaging patterns.
- Suggests that prompt diagnosis can mitigate patient harm and reduce healthcare costs.
