Anti-Ganglioside Antibody Negative Miller Fisher Syndrome with Atypical Features: A Case Report

Abstract

Miller Fisher Syndrome (MFS), a variant of Guillain Barre Syndrome (GBS), is an immune-mediated neuropathy presenting with the classical clinical triad of ophthalmoplegia, ataxia, and areflexia. Although the clinical triad is the cardinal diagnostic clue, it can also present with a variety of other atypical neurological symptoms and signs beyond the classical triad. IgG anti-GQ1b antibodies are a powerful serological marker for the diagnosis of MFS, however, they can be absent in 10-15% cases of MFS. Here, we are describing a case of a 55-year old lady with an anti-ganglioside negative case of MFS with ptosis and bulbar palsy, who improved with IVIg.
