Suspected case of Guillain-Barré syndrome (GBS)
A 14-year-old girl was admitted to a nursing home one month before presenting at our hospital with fever and dyspnea that had persisted for one week and for two days, respectively.
One day after admission to the local hospital, mechanical ventilation was applied under a diagnosis of pneumonia. Thereafter, her general condition improved under antibiotic therapy, but three attempts to wean her from the mechanical ventilation failed so she was transferred to our hospital on day 32.
Intensive reviews of her medical records from the local hospital and her medical history indicated that muscle weakness had started to spread from the lower to the upper limbs two days before admission to the nursing home, peaked on day 16 and continued to day 32. Based on the clinical findings of muscle weakness in the limbs and phrenic nerve palsy presenting as a decrease in tidal volume with a history of difficulty in weaning off mechanical ventilation, we suspected Guillain-Barré syndrome (GBS).
