Forme fruste anti-GQ1b-negative Miller Fischer syndrome masquerading as posterior circulation stroke

Miller Fischer syndrome (MFS) is a variant of Guillain–Barré syndrome first described in 1956 and is characterised by the clinical triad of ophthalmoplegia, ataxia and areflexia. However, since its discovery, forme fruste and overlapping syndrome have been described. A forme fruste of MFS implies an attenuated form where not all of the clinical triad are present.
