Abstract:
The association of acute myelopathy and encephalopathy is reported in a 13-year-old boy. Signs and symptoms of infectious mononucleosis, presence of heterophile antibodies, anticapsid antibodies and Epstein-Barr virus DNA detected in cerebrospinal fluid, disclosed a primary or reactivated infection by Epstein-Barr virus. Outcome was rapid and benign with complete clinical recovery in 1 month, after pulse therapy with methylprednisolone. Epstein-Barr virus is a known agent related to acute disseminated encephalomyelitis, by immune mediated mechanisms. However, in this case, cortical involvement in magnetic resonance imaging, short time between infectious mononucleosis and central nervous system manifestations, and the presence of viral DNA in cerebrospinal fluid, raised the possibility of a direct action of the virus in central nervous system. Acute myelopathy associated to Epstein-Barr virus encephalitis has been rarely reported in children.
Insights
A rare case of acute myelopathy and encephalopathy in a 13-year-old boy was linked to Epstein-Barr virus infection. Prompt treatment led to a full recovery, suggesting potential direct viral CNS involvement.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Neuroimmunology
Background:
- Epstein-Barr virus (EBV) is a common human herpesvirus.
- EBV is known to cause infectious mononucleosis.
- EBV is implicated in immune-mediated neurological disorders like acute disseminated encephalomyelitis (ADEM).
Observation:
- A 13-year-old boy presented with acute myelopathy and encephalopathy.
- Clinical and laboratory findings confirmed infectious mononucleosis due to EBV.
- Cerebrospinal fluid analysis revealed Epstein-Barr virus DNA.
Findings:
- The patient experienced cortical involvement on MRI.
- Central nervous system (CNS) manifestations appeared shortly after infectious mononucleosis.
- The presence of EBV DNA in CSF suggested a potential direct viral invasion of the CNS.
- Acute myelopathy and EBV encephalitis are rarely reported together in children.
Implications:
- This case highlights a rare presentation of EBV infection in the CNS.
- It raises the possibility of direct EBV neuroinvasion beyond typical immune-mediated mechanisms.
- Rapid diagnosis and pulse methylprednisolone therapy resulted in complete recovery.
- Further research may elucidate the direct role of EBV in pediatric CNS disorders.
