Chest CT-Bullitis

Bullae


Example

  • Clinical History: 82 y/o WM with active tobacco abuse, congestive heart failure, pulmonary hypertension, and home O2-dependent bullous emphysema who was admitted with COPD exacerbation and pneumonia with bullitis (sputum and blood cultures were negative in this case)
  • Radiologic Features
    • Note the air-fluid levels within the bullae
    • Note the emphysematous changes in the surrounding right lung, consistent with severe underlying emphysema
    • Also note that the patient had a pre-existing bullae in this location prior to the infection, making the diagnosis of necrotizing pneumonia with cavitation (which can appear similarly) less likely
