Weakness and diplopia in a 4-year old boy. An unusual Diagnosis

Ptosis, diplopia, and overall weakness in children may have serious underlying causes such as myasthenia, botulism, Guillain-Barré syndrome, and poisoning, which require a systematic and timely evaluation and proper management.(1,2,3) In pediatrics, clinical presentations may be atypical, and diagnostic overlap sometimes makes the final diagnosis challenging. This can be addressed through taking accurate history, performing a physical exam, conducting a comprehensive assessment, and using appropriate diagnostic algorithms.
