Unlike the classic ascending weakness or paralysis that is characteristic of the more typical types of GBS, neurological deficits follow a top down pattern in MFS, starting with diplopia in the eyes caused by external opthalmoplegia-the most common presenting symptoms. Upper respiratory infection is the most commonly described prodromic entity, followed by gastrointestinal illness. Campylobacter jejuni and Haemophilus influenza have been the most commonly implicated pathogens however, multiple others are also associated, including Mycoplasma pneumonia, and cytomegalovirus. 2, 5 As in GBS, an antecedent infectious illness can be identified in the majority of MFS cases. 4 There is an established male predominance at a ratio of 2:1 and a mean age of onset of 43.6 years, although cases of MFS have been reported in all age ranges. 1 – 3 Aptly named, Miller Fisher Syndrome (MFS) is a geographically variable variant of GBS observed in about 1% – 5% of all GBS cases in Western countries, yet up to 19% and 25% in Taiwan and Japan, respectively. 1 Fisher recognized both the uniqueness of this cluster of clinical signs and its relationship to what is now considered a heterogeneous group of immune-mediated neuropathies classified under Guillain-Barré Syndrome. It was subsequently reported as a variant of Guillain-Barré Syndrome (GBS) by Charles Miller Fisher in three clinical cases in 1956. The triad of ataxia, areflexia, and opthalmoplegia was first described by James Collier in 1932. Our suspected diagnosis of MFS was serologically confirmed with positive anti-GQ1b antibody titer and the patient was successfully treated with Intravenous immune globulin (IVIG). The patient exhibited the classic triad of ataxia, areflexia, and opthalmoplegia characteristic of MFS, but also had less typical signs and symptoms making for a more challenging diagnostic workup. The following case report is that of a patient who presented with generalized weakness, somatic pain, inability to walk, and diplopia following an upper respiratory illness. ![]() A self-limiting course is typical of MFS. Serological confirmation with the anti-GQ1b antibody is available and allows for greater diagnostic certainty in the face of confounding symptoms. It is largely a clinical diagnosis based on the cardinal clinical features of ataxia, areflexia, and opthalmoplegia, however, other neurological signs and symptoms may also be present. Miller Fisher Syndrome (MFS) is a rare variant of Guillain-Barré Syndrome (GBS) that has a geographically variable incidence. ![]()
