Guillain-Barré syndrome is an acute demyelinating polyneuropathy that presents clinically with muscular weakness and autonomic disorders in its typical form, while the sensory symptoms usually go unnoticed.
We describe the clinical history of a male patient with acute flaccid quadriparesis and sensory disorders such as paresthesia and allodynia that hinder diagnosis within the initial approach.
Complete diagnostic work up confirmed the presence of Guillain-Barré syndrome. Although the sensory symptoms confused the diagnosis during admission, it is important to highlight that pain is a frequent manifestation of this disorder, being underestimated in many patients.
