Cicatrization atelectasis results from diminution of volume as a sequela of severe parenchymal scarring and is usually caused by granulomatous disease or necrotizing pneumonia. Replacement atelectasis occurs when the alveoli of an entire lobe are filled by tumor (eg, bronchioalveolar cell carcinoma), resulting in loss of volume.
