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.
