Inflammatory myopathies rarely cause sensory issues. This study highlights two cases with unexpected sensory problems, likely from immune damage to dorsal root ganglia, emphasizing diagnostic imaging and nerve tests.

Area of Science:

  • Neurology
  • Immunology
  • Neuroscience

Background:

  • Inflammatory myopathies (IM) are autoimmune disorders primarily affecting skeletal muscle.
  • Sensory abnormalities are uncommon manifestations in patients diagnosed with IM.

Observation:

  • This report details two patients diagnosed with IM who exhibited unusual sensory deficits.
  • One patient had dermatomyositis, and the other had inclusion-body myositis.

Findings:

  • The patients' sensory abnormalities were attributed to probable immune-mediated damage affecting the dorsal root ganglia.
  • This suggests a potential, albeit rare, extra-muscular autoimmune manifestation in IM.

Implications:

  • The findings underscore the necessity of considering dorsal root ganglia involvement in IM patients presenting with sensory symptoms.
