Miller-Fisher syndrome, Guillain-Barre syndrome with ophthalmoplegia, Bickerstaff s brainstem encephalitis and acute ophthalmoplegia share some clinical features, and common anti-GQ1b IgG antibody and these are introduced as anti-GQ1b antibody syndrome. These syndromes mostly present with paralysis of extraocular muscles and internal ophthalmoplegia rarely occurs. We report a case of acute isolated bilateral internal ophthalmoplegia associated with anti-GQ1b IgG antibody.

Recently, we encountered a man with isolated bilateral sixth nerve palsies and areflexia whose titer of anti-GQ1b IgG antibody was elevated. We propose that bilateral sixth nerve palsies can be the sole manifestation of "anti-GQ1b antibody syndromes" and that patients with isolated bilateral sixth nerve palsies should be administered an anti-GQ1b antibody test for the diagnosis of acute immune-related neuropathy.

Guillain-Barré syndrome (GBS) and Miller Fisher syndrome (MFS) can present with overlapping features. A 56-year-old female developed ptosis and diplopia after an upper respiratory infection, and presented with facial palsy, dysarthria, brachial weakness, ataxia, and areflexia. Mild weakness of both legs appeared after a few days. Anti-ganglioside complex antibody were positive to IgG GM1/GQ1b and GQ1b/sulfatide antibodies. The present case suggests that the manifestation of overlap between MFS/PCB variants and GBS could be caused by antiganglioside complex antibodies.

Acute ophthalmoparesis that includes the oculomotor, trochlear, or abducens nerve may occur as an initial presentation of Miller Fisher syndrome (MFS). The symptoms of MFS or variant forms of Guillain-Barre syndrome are pathogenically related to anti-GQ1b antibodies. We report a case of a 36-year-old man with unilateral isolated abducens nerve palsy associated with anti-GM1 antibody. To the best of our knowledge, this is the first report of unilateral isolated abducens nerve palsy with positivity for anti-GM1 immunoglobulin M antibody.

A flaccid tetraparesis in Bickerstaff's brainstem encephalitis (BBE) is presumed to be a sign of overlapping Guillain-Barr$\acute{e}$ syndrome (GBS). In addition, BBE and Fisher syndrome, which are clinically similar and are both associated with the presence of the immunoglobulin G anti-GQ1b antibody, represent a specific autoimmune disease with a wide spectrum of symptoms that include ophthalmoplegia and ataxia. A 2-year-old boy presented with rapidly progressive ophthalmoplegia, ataxia, hyporeflexia, weakness of the lower extremities, and, subsequently, disturbance of consciousness. He experienced bronchitis with watery diarrhea and had laboratory evidence of recent infection with Epstein-Barr virus (EBV). He was diagnosed as having overlapping GBS and BBE associated with EBV and received treatment with a combination of immunoglobulin and methylprednisolone, as well as acyclovir, and had recovered completely after 3 months. In addition, he has not experienced any relapse over the past year. We suggest that combinations of symptoms and signs of central lesions (disturbance of consciousness) and peripheral lesions (ophthalmoplegia, facial weakness, limb weakness, and areflexia) are supportive of a diagnosis of overlapping GBS and BBE and can be helpful in achieving an early diagnosis, as well as for the administration of appropriate treatments.
