An Atypical Case of Miller Fisher Syndrome with Multiple Autoimmunity.

Miller Fisher syndrome (MFS) is a rare variant of Guillain-Barré syndrome that is characterised by ataxia, ophthalmoplegia, and areflexia. Its relation with other autoimmune diseases is scarcely found in the literature, and in those few cases, treatment has been especially difficult. We report a case of a 28-year-old woman who presented with ophthalmoplegia and ptosis, later developing facial palsy and hyporeflexia. She had positive GD1a, GT1a, GQ1b antibodies confirming MFS. She also had positive antinuclear and lupus anticoagulant antibodies confirming antiphospholipid syndrome. She had a mild clinical course. MFS can present with multiple autoimmunity; it is unclear if there is cross-reactivity due to myelin damage.
