Compressive atelectasis

Compressive atelectasis refers to a form of lung atelectasis due to compression by a space-occupying process.

Some authors describe it as a subtype of passive (relaxation) atelectasis where the reduction in lung volume is greater than its normal relaxed state . Whereas others describe it as the intrapulmonary counterpart of passive (relaxation) atelectasis due to an intrapulmonary mass lesion .
