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. In this report, a case of MFS is highlighted that was mistakenly treated as posterior circulation stroke, as well as the challenges faced in reaching the correct diagnosis and hence the appropriate treatment.
