Recurrent Miller-Fisher syndrome overlapping Guillain-Barrè syndrome and Bickerstaff brainstem encephalitis: A case report

Bickerstaff’s brainstem encephalitis mimicking herpetic encephalomyelitis in a liver transplant patient with anti-GQ1b antibodies

A woman in her late 70s with a history of liver transplant presented with ophthalmoplegia, ataxia, areflexia, positive Babinski’s sign and reduced consciousness. This followed an antecedent illness in the form of a herpes zoster infection. MRI of the brain/spinal cord, cerebrospinal fluid analysis with viral PCR and routine blood tests were normal, and tacrolimus neurotoxicity was ruled out. Serum anti-GQ1b antibodies were positive. A diagnosis of Bickerstaff’s brainstem encephalitis was made, forming part of the continuum that involves Miller-Fisher syndrome, entitled the ‘anti-GQ1b syndrome’. Complete recovery ensued without intravenous immunoglobulins or plasma exchange. The role of monitoring anti-ganglioside pattern change to predict or confirm disease recurrence and disease severity is further discussed.

Recurrent Guillain-Barré syndrome presenting as pharyngeal-cervical-brachial variant with three species of ganglioside antibodies:case report

BACKGROUND

Guillain-Barré syndrome (GBS) is generally considered to be monophasic, and recurrent GBS (RGBS) is very rare. Pharyngeal-cervical-brachial (PCB) is a less common variant of GBS. There have been no cases reported describing RGBS showing different phenotype presenting as PCB variant with three species of ganglioside antibodies.

CASE PRESENTATION

 We report a case of a 77-year-old female patient with GT1a, GD1a and sulfatide-seropositive PCB-GBS after prior episode of AMAN-GBS 13 years ago. Our patient showed oropharyngeal and cervicobrachial weakness associated with areflexia in the upper limbs and partially improved after 5 days of IVIG and physiotherapy.

CONCLUSION

This study reports a rare case characterized as recurrent GBS after a long period, showing different phenotypes in different episodes with three different species of ganglioside antibodies. Further studies are required to obtain better understanding of RGBS and PCB variant.
