Abstract

Sjögren’s syndrome (SS)-associated polyradiculopathy is rarely reported. A 51-year-old woman presented with a history of gradual weakness in all four extremities for several months. Based on electrophysiological studies, spinal magnetic resonance imaging and cerebrospinal fluid examination, inflammatory polyradiculopathy was confirmed. During a search for the aetiology, the patient was ultimately diagnosed with SS. This study introduces SS-associated polyradiculopathy that primarily presented with motor symptoms, thus mimicking motor neuron disease.
