However, early or atypical presentations may lack the hallmark diagnostic features, such as elevated cerebrospinal fluid (CSF) protein or abnormal magnetic resonance imaging (MRI) findings, creating a diagnostic challenge. We present the case of a 46-year-old woman who developed progressive distal paresthesias, gait instability, perioral numbness, hoarseness, and later right foot-drop following a viral-like illness. Initial evaluation revealed normal CSF protein levels, an unremarkable MRI of the brain and spine, and preserved strength, leading to diagnostic uncertainty. Despite these findings, the clinical pattern raised suspicion for early sensorypredominant GBS, and intravenous immunoglobulin therapy was initiated with subsequent clinical improvement. This case underscores the importance of maintaining high clinical suspicion for GBS inpatients with compatible symptoms, even in the absence of classical diagnostic findings, to ensure timely intervention and prevent progression.  \nCategories: Neurology, Internal Medicine, Allergy/Immunology  \nKeywords: acute inflammatory demyelinating polyradiculoneuropathy, cerebrospinal fluid, diagnostic challenge, guillain‒barre syndrome, intravenous immunoglobulin, nerve conduction studies, peroneal neuropathy, sensory neuropathy  \nIntroduction  \nGuillain-Barré syndrome (GBS) is an acute, immune-mediated polyradiculoneuropathy that typically follows a viral or bacterial infection and is characterized by rapidly progressive, symmetric weakness and areflexia. The annual incidence ranges from one to two cases per 100,000 people and remains a leading cause of acute flaccid paralysis worldwide [1] . GBS encompasses several heterogeneous pathophysiologic subtypes, including acute inflammatory demyelinating polyradiculoneuropathy (AIDP), acute motor axonalneuropathy (AMAN), acute motor and sensory axonal neuropathy (AMSAN), and Miller Fisher syndrome. In North America, AIDP is the most prevalent subtype and is caused by immune-mediated demyelination of peripheral nerves and nerve roots. The classic diagnostic hallmark is albuminocytologic dissociation, elevated cerebrospinal fluid (CSF) protein without pleocytosis, along with demyelinating changes on nerve conduction studies [2] .  \nHowever, atypical and early presentations can lack these characteristic findings, creating significant diagnostic uncertainty. Sensory-predominant variants, for instance, may present with distal paresthesias, pain, or gait disturbance before weakness develops, sometimes mimicking peripheral mononeuropathies orradiculopathies [3] . In such cases, both CSF and magnetic resonance imaging (MRI) may appear normal early in the disease course, and electrodiagnostic abnormalities may not yet be evident.  \nEarly recognition remains essential, as prompt initiation of intravenous immunoglobulin (IVIG) or plasma exchange can reduce neurological progression and long-term disability. We present a case of early sensorypredominant GBS with normal CSF and MRI findings, highlighting the importance of maintaining clinical suspicion ","cbCaijmZbtrYjZ7j","https://ap.wps.com/l/cbCaijmZbtrYjZ7j","pdf",10471029,"English","# Introduction\n# Case Presentation\n# Diagnostic Evaluation\n# MRI Findings\n# How to Cite","[{\"question\":\"Why can Guillain-Barré syndrome be difficult to diagnose early?\",\"answer\":\"Early or atypical presentations may not show classical hallmarks such as elevated CSF protein or abnormal MRI findings, and electrodiagnostic abnormalities may be absent at first.\"},{\"question\":\"What symptoms did the reported patient develop?\",\"answer\":\"The patient experienced progressive distal paresthesias, perioral numbness, hoarseness, gait instability, and later right foot-drop following a viral-like illness.\"},{\"question\":\"What diagnostic results were initially normal in this case?\",\"answer\":\"Initial evaluation showed normal CSF protein levels, unremarkable brain and spine MRI, preserved strength, and no acute intracranial abnormalities on imaging.\"}]","Early Sensory-Predominant Guillain-Barré Syndrome With Normal Cerebrospinal Fluid and MRI Findings: A Diagnostic Challenge | PDF",1790703271,23]
