Systemic Lupus Erythematosus Initially Presenting as Acute Motor and Sensory Axonal Neuropathy Variant of Guillain-Barre Syndrome in a Healthy Active Duty Female.

Guillain-Barre syndrome (GBS) is an acute monophasic immune-mediated polyradiculoneuropathy characterized by rapidly evolving ascending weakness, mild sensory loss, and hypo- or areflexia, typically progressing to peak symptoms over the course of 4 weeks. The precise mechanism is unclear but is proposed to be an immune-mediated reaction with the generation of antibodies against peripheral nerves triggered by a preceding viral infection. Acute motor and sensory axonal neuropathy (AMSAN) is a rare and severe variant of Guillain-Barre syndrome with limited published literature.
