Abstract:Miller-Fisher syndrome combines the clinical trial, ophthalmoplegia, ataxia, and diffuse osteotendinous areflexia. It is a variant of Guillain-Barré syndrome, from which it differs by the positivity of anti-GQIb antibodies in the serum. Its clinical evolution is most often favorable. In addition to the classical form, exceptional clinical forms, either incomplete or extended to the confines of the SGB are also described. We thus describe a case of extensive SMF, overlapping with the SGB, associating in additio… Show more
“…The patient presented clinically and electrophysiologically with an overlapping MFS and GBS syndrome. In the literature, several overlapping syndromes between GBS and MFS have been described [ 2 , 5 ], and cranial nerves involvement seems to be the common point between these forms [ 5 , 6 ].…”
Background
Polyradiculoneuropathy following infection with varicella zoster virus (VZV) is rare and most of the time, happens in the context of reactivation of latent VZV. We report a case of acute polyradiculoneuropathy following primary infection with VZV marked by atypical clinical features raising the hypothesis of a para-infectious disease.
Case presentation
We describe a 43-years-old male who developed ataxia, dysphagia, dysphonia, and oculomotor disorders (vertical binocular diplopia and bilateral ptosis) followed by quadriplegia with areflexia which occurred 4 days later. The patient had a history of varicella that occurred 10 days before the onset of these symptoms. Nerve conduction study revealed features consistent with an acute motor-sensory axonal neuropathy (AMSAN). Anti-ganglioside antibodies were negative.
Based on clinical presentation and ancillary examination, we retain the Miller Fisher/Guillain-Barré overlap syndrome diagnosis.
The patient was treated with high doses of methylprednisolone but the evolution of the disease was nevertheless marked by a complete recovery six weeks after onset of symptoms.
Conclusion
GBS following varicella is a rare but severe disease occurring most often in adults and marked by greater involvement of the cranial nerves. Its clinical features suggest that it is a para-infectious disease. Antiviral therapy has no effect on the course of the disease but its administration within the first 24 h after the onset of chickenpox in adults can prevent its occurrence.

“…According to their clinical features, GBS and its variant MFS can be classified into different subtypes which together form a continuous spectrum of several overlapping syndromes. The involvement of cranial nerves other than the typical oculomoteur ones, seems to be more frequent in the forms of MFS-GBS overlap: facial nerve in 30 to 50%, glossopharyngeal (IX), vagus (X), large hypoglossus (XII), responsible for disorders of swallowing and dysphonia, in 13% of cases [5,6]. The nasal voice related to palate paresis has been rarely described in MFS [7,8].…”
Miller Fisher Syndrome (MFS) is a rare variant of Guillain-Barré Syndrome (GBS). It is largely a clinical diagnosis based on the classical features of ataxia, areflexia, and opthalmoplegia. Its clinical evolution is most often favorable. However, other neurological signs and symptoms may also be present. Supportive laboratory studies (positivity of antibodies, CSF albumin-cytological dissociation and nerve conduction studies) are useful especially in uncommon presentations. We report a case of a 74-year-old patient who exhibited dysphonia and difficulty to swallowing previously to the classic triad of ataxia, areflexia, and opthalmoplegia, characteristic of MFS. CSF analysis demonstrates an albumin-cytological dissociation but anti-GQ1b antibody were negative. The patient has spontaneously and completely recovered after several weeks.
