When performed on primary spontaneous pneumothorax patients, CT detects multiple blebs and bullae in the setting of negative chest radiographic findings. This may not impact management, in that there has been no correlation between number of blebs and recurrence. However, CT may have a role in secondary spontaneous pneumothorax, especially to differentiate from giant bullous emphysema.
