Axonal sensory-motor polyneuropathy in ankylosing spondylitis: A case report.

KEY CLINICAL MESSAGE: In ankylosing spondylitis cases, axonal-type sensory-motor polyneuropathy is a rare manifestation and should be considered an underlying etiology in patients with unexplained neuropathy.

ABSTRACT: This case report discusses a 45-year-old male diagnosed with ankylosing spondylitis (AS), a chronic inflammatory disorder affecting the axial skeleton and peripheral joints. The patient presented with polyneuropathy, characterized by tingling and numbness in the upper and lower limbs, which is an uncommon manifestation of AS. After undergoing various tests, including CT scans and EMG-NCV, no secondary cause for the neuropathy was identified; AS was considered the etiology of the patient's axonal-type sensory-motor polyneuropathy.
