RESUMO
We discuss a patient who presented with bilateral VI and VII cranial nerve palsies, symmetric upper and lower limb weakness and areflexia, 2 weeks following an flu-like illness. At presentation, there was no papilloedema, and her visual function was normal. Cerebrospinal fluid analysis and electrophysiology supported the diagnosis of Guillain-Barré Syndrome (GBS). She received intravenous immunoglobulins. She subsequently developed headaches and vision loss. Funduscopy demonstrated severe papilloedema with visual acuity of 6/18 right eye, 6/12 left eye with bitemporal visual field depression. Lumbar puncture revealed elevated opening pressure with high protein and normal cell count. She received acetazolamide. There was resolution of papilloedema and normal visual function at 3 months. Of note, the patient's body mass index was 17 kg/m2Our case highlights the rare occurrence of papilloedema in GBS, reiterating the importance of performing funduscopy on patients with any neurological diagnosis. Early detection and prompt management of papilloedema can prevent permanent vision loss.
