Bullous emphysema
Three photos of emphysematous bullae. Bullae can develop in the subpleural region in any type of emphysema. These
large air-containing spaces can be very thin-walled. In paraseptal emphysema, involvement is most striking near the pleura,
often leading to spontaneous pneumothorax in young persons when a bleb ruptures. Some regard the term bleb as
synonymous with bulla but others limit the use of the term bullae to lesions larger than 1 cm in diameter.
