CT densitovolumetry shows the attenuation mask. It is often asymptomatic, but it can be associated with spontaneous pneumothorax in young adults. Morgan MD, Denison DM, Strickland B. Because paraseptal emphysema occurs adjacent to the pleura and septa and emphysema animal models have marked changes in capillary segments (i.e., a higher number of nonconnecting segments) on the pleural surface , disruptions of pulmonary and/or pleural capillaries might also contribute to paraseptal emphysema.

Most also have separate centrilobular emphysema; Most common in young men, mostly in smokers; Clinical Findings. Paraseptal emphysema refers to a morphological subtype of pulmonary emphysema located adjacent to the pleura and septal lines with a peripheral distribution within the secondary pulmonary lobule. Paraseptal emphysema affects the distal aspects of the lung acinus – the alveolar ducts and sacs in the lung periphery, with areas of destruction often marginated by the interlobular septa. A secondary pulmonary lobule described by the interstitial septa can have as many as 100 acini (blue groups, the biggest one showing a pulmonary lobule containing about 35 acini) (Corrêa da Silva, 2001).

At the time of initial writing, approximately 210 million people are affected worldwide leading to 3 million deaths annually 1. It differs from centrilobular and panlobular emphysema by involving the distal portion of the acinus. When the retrosternal space (defined as the space between the posterior border of the sternum and the anterior wall of the mediastinum) is larger than 2.5 cm, it is highly suggestive of overinflated lungs.

PMID: 30464438 PMCID: PMC6214583 DOI: 10.2147/COPD.S178109 Abstract Introduction: There are no studies analyzing the relationship between emphysema and lung cancer (LC). This is the typical appearance of paraseptal emphysema, which is caused by destruction of alveolar ducts and alveoli in the periphery of the secondary pulmonary lobules. Paraseptal emphysema can develop as a result of a long-term smoking habit.
