Insights
Epstein-Barr virus infection in children can mimic serious neurological conditions like encephalitis. This study found that visual hallucinations can be a peculiar symptom, and the condition often resolves without specific treatment.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Neurovirology
Background:
- Epstein-Barr virus (EBV) infection can present with diverse neurological manifestations in children.
- Differentiating EBV-related neurological illness from other conditions like encephalitis or neurodegenerative diseases is clinically challenging.
Purpose of the Study:
- To retrospectively analyze the clinical presentation, diagnostic findings, and outcomes of children with Epstein-Barr virus infection and neurological symptoms.
- To highlight visual hallucinations as a potential indicator of EBV encephalitis.
Main Methods:
- Retrospective case series of nine Chinese children (1.5–14 years) with confirmed EBV infection and neurological symptoms.
- Clinical evaluation, electroencephalography (EEG), and neuroimaging (CT, MRI, HMPAO SPECT) were utilized.
- Neurological follow-up assessments were conducted.
Main Results:
- Patients presented with varied neurological signs including altered consciousness, visual hallucinations, cranial neuropathies, and sphincter dysfunction.
- EEG revealed focal spikes in multiple cortical areas.
- Eight out of nine patients showed normal neurological recovery; one improved from spastic quadriparesis.
Conclusions:
- Epstein-Barr virus encephalitis in children can present with unusual symptoms like visual hallucinations.
- The condition appears to be self-limiting, with most patients achieving good neurological recovery without specific antiviral therapy.
Abstract:
Nine Chinese children (four males, five females) in whom serology showed Epstein-Barr virus infection were studied retrospectively. They were from 1.5 to 14 years of age. Various symptoms and signs, including disturbance of consciousness, visual hallucination, cranial neuropathies and sphincter dysfunction, led to initial clinical impressions of encephalitis, encephalomyelitis and neuro-degenerative disease. Electroencephalography showed focal spikes over the frontal, occipital, temporal and parietal areas. The patients underwent brain computed tomography and/or magnetic resonance imaging, and three of them underwent HMPAO SPECT. Eight patients appeared normal neurologically during follow-up, and the single patient who had spastic quadriparesis improved gradually. Though visual hallucination is not a specific presentation, it is a peculiar picture of Epstein-Barr virus encephalitis. Epstein-Barr virus encephalitis seemed to be self-limiting without specific treatment in this group.
