Background: GBS is an acute inflammatory polyneuropathy resulting from an immune response after infection. Characterized as an ascetic, progressive, selflimiting flaccid tetraparesis. It has several phenotypic presentations, which one is AMAN. The treatment’s based on use of intravenous immunoglobulin (IGIV) and plasmapheresis (PLEX). Methods: A literature review of the PubMed and UpToDate databases using descriptors “GBS” and “AMAN” between 2014-2020. Objectives: Report a case of GBS, addressing AMAN variant; a literature review with therapeutic and diagnostic possibilities. Case report: DTS, 32y, male, admitted with a picture of flaccid, limp asymmetrical tetraparesis, with an asymmetrical pattern, predominant in lower limbs, without sensory symptoms. Progressive evolution, onset of motor symptoms on the 8th day after self-limited diarrhea. CSF on 3rd day of onset of motor symptoms without dissociation cytological protein - CN: 62 / Ptn: 80.1mg / dl. Repeated CSF on the 10th day with CN: 27 / Ptn: 215 mg / dl. electroneuromyography 16/04: electrophysiological examination shows motor neuropathy of axonal pattern with signs of denervation in activity, findings compatible with axonal neuropathy. IGIV was performed for 5 days, without complications. Results: The diagnosis of GBS is based on CSF clinical criteria and findings on electroneuromyography. AMAN is a phenotypic variant characterized by purely motor and axonal impairment. The therapeutic options proven effectiveness are PLEX, and IGIV. Conclusion: Studies demonstrates that there’s no difference in effectiveness between PLEX and IGIV, the choice of treatment being dependent on socioeconomic and patient-related factors.
