a case of guillain-barre syndrome presented with bilateral pseudo-internuclear ophthalmoplegia

guillain-barre syndrome (gbs) or acute idiopathic polyradiculoneuritis is an acquired immune-mediated inflammatory and mainly demyelinating disorder of the peripheral nervous system. cranial nerves are affected in over 50% of all cases, with the facial nerves being affected the most. it uncommonly presents as atypical forms such as brachial pharyngeal variant, miller fisher and other restricted forms. herein, we reported a 44 year old male with gbs who presented with diplopia and bilateral pseudo- internuclear ophthalmoplegia. initially, the patient was confused as a case of multiple sclerosis but finally diagnosis of gbs was made. although internuclear ophthalmoplegia is a typical feature of multiple sclerosis, it may be seen as a rare manifestation of gbs as well.
