    Paraseptal emphysema, also called distal acinar emphysema, relates to emphysematous change next to a pleural surface, or to a fissure. [ 18 ] [ 26 ] The cystic spaces known as blebs or bullae that form in paraseptal emphysema typically occur in just one layer beneath the pleura.

    The most common disease causing blebs or bullae is paraseptal emphysema though centrilobular emphysema may sometimes be involved. [1] Other conditions associated with lung bullae are: Alpha 1-antitrypsin deficiency [6] Marfan syndrome [6] Ehlers–Danlos syndromes [6] Cocaine smoking [6] Sarcoidosis [6] HIV/AIDS [6] Intravenous substance abuse [6]

Pneumoperitoneum (or peritoneal emphysema), air or gas in the abdominal cavity.The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.

    Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...

    en.wikipedia.org/wiki/Ground-glass_opacity

    Centrilobular GGOs refer to opacities occurring within one or multiple secondary lobules of the lung, which consist of a respiratory bronchiole, small pulmonary artery, and the surrounding tissue. [3] A defining feature of these GGOs is the lack of involvement of the interlobular septum.

    An axial CT image showing bullous emphysema of the lungs. There are larger air pockets on the right than left. Bullous emphysema is a condition seen in patients with chronic obstructive pulmonary disease (COPD). The units making up the substructure of the lung (alveoli) become permanently enlarged due to the destruction of their walls.

    Combined pulmonary fibrosis and emphysema (CPFE), describes a medical syndrome involving both pulmonary fibrosis and emphysema. [ 1 ] [ 2 ] The combination is most commonly found in male smokers. Pulmonary function tests typically show preserved lung volume with very low transfer factor.
