Guillain-Barrè syndrome (GBS) is an acute, paralyzing, inflammatory peripheral nerve disease, featured by monophasic disease course, symmetrical limb weakness and areflexia. Several pathologies can mimic the clinical presentation of GBS, making hard the differential diagnosis for patients complaining of acute flaccid paralysis. In this paper we describe three cases of different neurological diseases presenting with acute motor symptoms mimicking GBS, reviewing the relevant literature on misdiagnosis of GBS.
