COVID-19

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
