Pulmonary bullae

Pulmonary bullae are focal regions of emphysema with no discenible wall which measure more than 1 cm in diameter 1-2. Some use the term pulmonary bleb for a 1-2 cm lesion, whereas others use the terms bleb and bulla interchangeably. They are often subpleural in location and may result in spontaneous pneumathoraces.

In some cases, bullae can be very large and result in compression of adjacent lung tissue.
