[edit] Discussion of Relapsing polychondritis

  • Relapsing polychondritis is characterized by recurrent episodes of cartilage inflammation
  • Most commonly affecting the ear, nose, joints, and the laryngeal and tracheal cartilage.
  • The upper airways are affected in greater than 50% of patients.
  • Diffuse tracheal inflammation is limited to the cartilage and perichondrium and does not affect the mucosa or submucosa.
  • Both the extrathoracic and intrathoracic trachea are involved.

[edit] Imaging Findings for Relapsing polychondritis

  • CT usually shows:
    • Wall thickening limited to the anterior and lateral tracheal walls (sparing of the posterior membrane)
    • Collapse of the cartilage
    • Narrowing of the tracheal lumen.
  • If cartilage calcification is present, the cartilage may appear thicker than normal.
  • The luminal narrowing may be fixed or tracheomalacia may be present.
