Abstract:
A patient who developed an acute brainstem syndrome following Mycoplasma pneumoniae respiratory infection is reported. MRI showed changes consistent with brainstem demyelination. Clinical features and laboratory investigations support an immune mediated mechanism with no evidence of direction CNS invasion. On the basis of this case and a review of the literature, we postulate two mechanisms for the development of M. pneumoniae associated CNS disease: direct CNS invasion causing meningitis and an immune-mediated acute disseminated encephalomyelitis (ADEM). This has obvious therapeutic implications.
Insights
Mycoplasma pneumoniae respiratory infections can cause acute brainstem syndrome, potentially through direct invasion or immune-mediated mechanisms like acute disseminated encephalomyelitis (ADEM). This finding has significant therapeutic implications for CNS disease.
Area of Science:
- Neurology
- Infectious Diseases
- Immunology
Background:
- Mycoplasma pneumoniae is a common respiratory pathogen.
- Central nervous system (CNS) complications following M. pneumoniae infection are rare but serious.
- The exact mechanisms underlying M. pneumoniae-associated CNS disease are not fully understood.
