[Isolated abducent nerve paralysis in infectious mononucleosis]

Area of Science:

• Pediatrics
• Infectious Diseases
• Neurology

Background:

• Infectious mononucleosis, often caused by the Epstein-Barr virus (EBV), exhibits diverse clinical presentations in children and adolescents.
• Accurate diagnosis is essential for appropriate management and understanding potential complications.

Observation:

• A case study of a 12-year-old girl presenting with isolated abducens nerve palsy is detailed.
• This neurological symptom, a form of mononeuritis, was the primary manifestation observed.

Findings:

• Specific serological tests for Epstein-Barr virus-specific antibodies were instrumental in identifying the parainfectious etiology.
• The diagnosis confirmed a link between EBV infection and the observed nerve palsy.

Implications:

• Highlights the importance of serological testing for EBV in pediatric cases with atypical neurological presentations.
• Suggests that isolated cranial nerve palsies in children may be an underrecognized manifestation of EBV infection.
• Emphasizes the role of pediatricians in utilizing specialized serological diagnostics for differential diagnosis.
