Magnetic resonance imaging (MRI) is valuable for diagnosing myopathy. This case highlights a unique lower extremity myopathy where MRI revealed sparing of the quadriceps muscle group, an unusual finding in myopathic conditions.

Area of Science:

  • Neurology
  • Radiology
  • Musculoskeletal Imaging

Background:

  • Magnetic resonance imaging (MRI) is a key diagnostic modality for evaluating myopathies.
  • Myopathic changes frequently affect multiple muscle groups due to underlying inflammatory, neuropathic, or neuromuscular disorders.

Observation:

  • This report details an unusual case of lower extremity myopathy.
  • The patient presented with myopathic changes identified via MRI.

Findings:

  • A unique finding was the sparing of the quadriceps muscle group on MRI.
  • This contrasts with typical patterns of myopathy where multiple muscle groups are involved.

Implications:

  • This case expands the spectrum of MRI findings in myopathy.

  • Understanding such unique presentations aids in accurate diagnosis and patient management.
  • Further research into muscle-specific patterns in myopathy is warranted.
