Pure Motor Axonal Neuropathy Associated with Sjögren's Syndrome: A Rare Case Report

Background

Peripheral nervous system involvement is a recognized extraglandular manifestation of Sjögren's syndrome (SjS), most commonly presenting as sensory or mixed sensorimotor axonal neuropathies. Pure motor axonal neuropathy is exceptionally rare in this context and may closely mimic anterior horn cell disorders, posing significant diagnostic and therapeutic challenges.
