Radiologic Testing and Findings

Characteristic Ultrasound findings include: 

  • Thickened pleural line
    • Pleural line thickening with uneven B lines can be seen in pulmonary fibrosis
  • B lines (multifocal, discrete, or confluent)
    • Focal B lines is the main feature in the early stage and in mild infection
  • Both non-translobar and translobar consolidations
  • Multilobal distribution of abnormalities
  • Alveolar interstitial syndrome is the main feature in the progressive stage in critically ill patients

Chest CT Findings:

  • Thickened pleura
  • Ground glass shadow and effusion
  • Pulmondary infiltrating shadow
  • Subpleural consolidation
  • Translobar consolidation
  • More than two lobes affected
  • Negative or atypical lung CT images in the early stage, then diffuse scattered or ground glass shadow as the disease progresses to lung consolidation
  • Pleural effusion is rare

Chest X-ray Radiographic Findings:

  • Bilateral interstitial pneumonia
  • Bilateral infiltrates common with gravitational distribution
  • Asymmetry if bacterial superinfection (secondary bacterial infection is uncommon)

Chest X-ray Clinical Findings from NCID Singapore 

  • 17/64 patients with initial normal CXR progressed to abnormal CXR
    • This was more common in older patients
    • Didn’t happen in any patients <30
    • Median was 7 days
  • Chest X-ray with pneumonia was considered a high-risk feature
