An Overlapping Case of Miller Fisher Syndrome and the Pharyngeal-Cervical-Brachial Variant of Guillain-Barré Syndrome

Learning Points: The overlap of Miller Fisher syndrome and pharyngeal-cervical-brachial variants of Guillain-Barré syndrome are rarely described in the literature but should be considered when multiple cranial nerves are involved with normal neuroimaging results, even with normal cerebrospinal fluid analysis.Due to similar clinical presentation, a misdiagnosis of cerebral ischaemia, botulism or ocular myasthenia gravis can delay treatment and put patients at risk.In its natural history, this syndrome evolves to respiratory arrest and death, but with accurate diagnosis and prompt treatment, the prognosis improves considerably.
