Abstract:
Mycoplasma pneumoniae infections usually produce respiratory symptoms, that only exceptionally involve the nervous system. In this case, the infection generally causes an encephalitic picture characterized by impaired consciousness and seizures, and by normal or non-specific neuroradiological findings. However, four cases of M. pneumoniae infection associated with symmetrical lesions in the putamen and its external surrounding areas, and with extrapiramidal symptoms, have been recently published. We present the case of a patient with a clinical picture characterized by confusion, fever, and seizures, associated with a M. pneumoniae infection. The MRI study showed two symmetrical lesions that involved the areas just outside the putamen and disappeared coinciding with her clinical improvement. The present case would support that the encephalopathy associated with the M. pneumoniae infection shows a tendency to involve a particular region of the brain. Our case might represent the minimal expression of these characteristic lesions, which in the most benign cases would involve the areas immediately outside the putamen, and in other instances the putamen as well.
Insights
Mycoplasma pneumoniae infection can rarely affect the brain, causing confusion and seizures. This case highlights characteristic brain lesions near the putamen, suggesting a specific pattern in M. pneumoniae-associated encephalopathy.
Area of Science:
- Neurology
- Infectious Diseases
- Neuroimaging
Background:
- Mycoplasma pneumoniae infections typically cause respiratory symptoms.
- Neurological involvement is rare, usually presenting as encephalitis with impaired consciousness and seizures.
- Recent literature suggests specific symmetrical lesions in the putamen and surrounding areas associated with M. pneumoniae infection.
Observation:
- A patient presented with confusion, fever, and seizures due to Mycoplasma pneumoniae infection.
- MRI revealed two symmetrical lesions in the brain regions external to the putamen.
- These lesions resolved as the patient's clinical condition improved.
Findings:
- The case supports a tendency for M. pneumoniae-associated encephalopathy to involve specific brain regions.
- The observed lesions, located immediately outside the putamen, may represent a minimal expression of characteristic brain abnormalities.
- This presentation could indicate a spectrum of M. pneumoniae-related neurological involvement, ranging from external putaminal lesions to putaminal involvement.
Implications:
- Recognizing this specific pattern of brain lesions is crucial for diagnosing M. pneumoniae-associated neurological complications.
- The findings contribute to understanding the neuroinvasive potential of Mycoplasma pneumoniae.
- Further research into the pathogenesis and clinical spectrum of M. pneumoniae encephalopathy is warranted.
