Epstein-Barr virus (EBV) encephalitis is a rare condition. This case highlights EBV encephalitis presenting with psychiatric symptoms in an immunocompromised patient, successfully treated with ganciclovir.
Area of Science:
- Neurovirology
- Infectious Diseases
- Immunocompromised Hosts
Background:
- Epstein-Barr virus (EBV) encephalitis is an uncommon neurological complication.
- Clinical presentations of EBV encephalitis are diverse.
- Diagnosis relies on detecting EBV in cerebrospinal fluid (CSF).
Observation:
- An immunocompromised patient presented with psychiatric symptoms and cognitive decline.
- The patient showed no typical neurological impairments or signs of infection.
- EBV encephalitis was diagnosed via CSF EBV-specific PCR and antibody testing.
Findings:
- Cerebrospinal fluid (CSF) EBV DNA was detected in the patient.
- Ganciclovir treatment led to clinical recovery.
- CSF EBV DNA levels normalized within six weeks of treatment.
Implications:
- EBV encephalitis should be considered in immunocompromised patients with unexplained psychiatric and cognitive symptoms.
- Early diagnosis and antiviral treatment (ganciclovir) can be effective.
- This case expands the known clinical spectrum of EBV encephalitis.
