Abstract

Miller Fisher syndrome (MFS), an acute demyelinating neuropathy, is characterised by a triad of areflexia, ataxia and ophthalmoplegia. It is the most common variant of Guillain-Barre Syndrome (GBS). In about 5.6%–7.1% of MFS cases, patients also suffer from progressive motor weakness of the limbs. This condition is termed MFS/GBS overlap syndrome. Whether it is in MFS or GBS, bilateral vocal cord paralysis (BVCP) is a rare manifestation with limited cases reported in the literature. We report an extremely rare case where a 65-year-old man developed BVCP in an MFS/GBS overlap syndrome. We have also reviewed previous case reports in the literature for comparison.
