Introduction: Juvenile myasthenia gravis (JMG) is a rare autoimmune disease acquired in childhood that included ۱۰-۱۵ percent of all cases of myasthenia gravis. Ocularmyasthenia gravis presents as ptosis with extraocular movement restriction and causes misdiagnosis when bilateral as third nerve palsy or congenital ptosis. Early diagnosishelps to prevent concerns and avoid further progression of disease. Method: This is a case report. I obtained data in our hospitalized patient in Ghaem Hospital, Mashhad, Iran. Results: Here, we introduced a case of ۴-year-old girl presented firstly by left eye ptosis, gait disorder and then respiratory distress, which was misdiagnosed by Guillain Barre Syndrome. She was represented by bilateral ptosis two months later that was diagnosed and managed by Mestinon and confirmed by EMG-NCV. Conclusions: Diagnosis and management of children with JMG should take account of their developmental needs, natural history of the condition, and side-effect profiles of treatment options.
