Bilateral Ptosis as the First Presentation of Guillain-Barre Syndrome.

Objective Guillain-Barre syndrome (GBS) is the most common cause of acute weakness in children. It has multiple variant forms with different presentations. A rare initial sign is ptosis. In this study, we present a 10-year-old girl with bilateral ptosis without opthalmoplegia followed by a weakness in extremities with a favourable response to intravenous immunoglobulin. Due to the patient's initial eyelid levators, myasthenia gravis was ruled out by a Tensilon test and electrophysiological studies. Our report highlights the possibility of GBS as a cause of isolated ptosis, especially in cases without ophthalmoplegia.
