# Atypical Guillain-Barré Syndrome in a Pediatric Patient With a Preceding Non-COVID-19 Coronavirus Infection: A Case Report

## TL;DR

A child developed atypical Guillain-Barré syndrome after a non-COVID-19 coronavirus infection and recovered with timely treatment.

## Contribution

Highlights atypical Guillain-Barré syndrome in a pediatric patient following non-COVID-19 coronavirus infection.

## Key findings

- The patient showed neurological deficits and dysautonomia after a coronavirus infection.
- Prompt diagnosis and targeted therapies led to significant recovery.
- Atypical presentations of Guillain-Barré syndrome can be managed effectively with timely intervention.

## Abstract

This study examines a four-year-and-one-month-old male with no significant past medical, family, or surgical history who initially presented to the pediatric clinic with cough, rhinorrhea, conjunctivitis, emesis, leg and arm pain, and increased difficulty ambulating. The patient was transferred to the emergency department and tested positive for a non-COVID-19 coronavirus infection. The patient was stabilized, given intravenous fluids, and discharged only to return to the clinic the next day with the onset of a headache, right eye ptosis, an inability to bear weight, and bilateral upper and lower extremity weakness resulting in an ataxic gait. In addition to the neurological deficits, the patient was found to have an elevated blood pressure and pulse. The patient was promptly transferred to a tertiary care clinic. Through exclusion of various differentials via testing, the patient was diagnosed and managed for atypical Guillain-Barré syndrome. Targeted therapies were initiated to prevent dysautonomia-associated morbidity. Following management, the patient’s condition vastly improved and he was admitted to rehabilitation bringing him back to optimal health. This study underlines the importance of prompt identification of atypical presentations of Guillain-Barré syndrome which may aid in avoiding preventable morbidity and mortality.
