What Is Centriacinar Emphysema

Centriacinar emphysema is the most common type of pulmonary emphysema mainly localized to the proximal respiratory bronchioles with focal destruction and predominantly found in the upper lung zones. The surrounding lung parenchyma is usually normal with untouched distal alveolar ducts and sacs.

How serious is centrilobular emphysema?

Centrilobular emphysema causes damage in the respiratory passages, and mainly affects the upper lobes in the centers of the functioning lung units. This damage can obstruct the flow of air from the lungs and make it difficult to breathe.

Is Paraseptal emphysema a cancer?

The risk of lung cancer decreases with the added presence of paraseptal emphysema (OR = 4.0, 95%CI: 3.6 to 34.9), losing this increased risk of lung cancer when it occurs alone (OR = 0.7, 95%CI: 0.5 to 2.6).
