Abstract:
Encephalitis in cat scratch disease is uncommon and usually reversible. The patient with cognitive impairment and severe memory disorder did not improve after a 30 month follow up. MRI revealed disseminated lesions in the white matter of the cerebral hemispheres.
Insights
Cat scratch disease encephalitis is rare and typically resolves. However, one patient experienced persistent cognitive impairment and memory loss, with MRI showing widespread brain lesions.
Area of Science:
- Neurology
- Infectious Diseases
- Neuroimaging
Background:
- Cat scratch disease (CSD) is a bacterial infection transmitted by cats.
- Neurological complications of CSD, such as encephalitis, are uncommon.
- CSD encephalitis is often reversible with treatment.
Purpose of the Study:
- To report a case of CSD encephalitis with an unusual, persistent clinical course.
- To highlight the potential for severe, long-term neurological sequelae in CSD.
Main Methods:
- Clinical case presentation.
- Review of patient's medical history and symptoms.
- Magnetic Resonance Imaging (MRI) analysis of brain lesions.
Main Results:
- The patient presented with cognitive impairment and severe memory disorder.
- Symptoms did not improve over a 30-month follow-up period.
- MRI revealed disseminated white matter lesions in the cerebral hemispheres.
Conclusions:
- CSD encephalitis can lead to prolonged or permanent neurological deficits.
- Persistent cognitive and memory deficits underscore the importance of recognizing CSD as a potential cause of encephalitis.
- Disseminated white matter lesions on MRI may indicate a poorer prognosis in CSD encephalitis.
