Bullous emphysema is generally seen in association with centriacinar emphysema and paraseptal emphysema. [40] Although a bullous emphysema is not a specific pathologic entity, a syndrome of giant bullous emphysema or vanishing lung syndrome has been described on the basis of clinical and radiologic features. Giant bullous emphysema is often seen in young men in association with large, progressive upper-lobe bullae that occupy a considerable volume of a hemithorax. Most patients with giant bullous emphysema smoke cigarettes, but this entity may also occur in nonsmokers.
