  • Etiology: Mycoplasma pneumoniae
  • Imaging CXR:
    — Bilateral diffuse bronchial wall thickening which leads to interstitial infiltrate
    — Can mimic viral pneumonia or bacterial pneumonia radiographically
  • DDX: Viral pneumonia and bacterial pneumonia
  • Complications:
  • Treatment: Antibiotics
  • Clinical: Walking pneumonia
