Paraseptal emphysema is a type of emphysema. Unlike other common types of emphysema, it mainly does harm to the distal airways and the air sacs close to the outer sides of the lungs. At the beginning of the disease, there can be few obvious symptoms. As a result, the patient may ignore the condition for several years.
Your disease is mild Paraseptal emphysema. It definitely will not progress if you had quit the smoking. In all likelihood, changes can reverse and can get better radiologically as well as symptomatically. Paraseptal would not progress to centrilobular if triggering or initiating event smoking has been stopped.
Paraseptal Emphysema The third and final morphological subtype of pulmonary emphysema is called paraseptal emphysema. This type is usually localized around the septae or pleura in the lungs. This is a thin sheet of tissue that’s located around the outside of the lungs and inside the chest cavity. Paraseptal emphysema usually involves the distal part of the secondary lobule and is therefore most obvious in subpleural regions.
Return to previous page A: The emphysematous lung is lucent compared to the normal transplant and contains fewer and smaller vessels. Focal lucencies, seen in patients who have centrilobular or paraseptal emphysema, are absent in this patient, as are paraseptal emphysema and bullae. B: Findings of panlobular emphysema are also evident in the middle lung. Paraseptal emphysema Upper lung Chest CT: emphysematous regions are represented by low attenuation areas (Eur Respir J 2016;48:216) Prognostic factors. Heard used the term paraseptal emphysema (PSE) to describe emphysematous lesions caused by selective destruction of the distal acinus (Fig 2, D), and subsequent reports have used it to describe lesions located near the pleural surface close to the chest wall and in the interlobar fissures.
All patients had chronic hypersensitivity pneumonitis (CHP). Centrilobular emphysema was most commonly seen with coexistent paraseptal emphysema in 5
Ground-glass attenuation areas are also commonly present. 2 Sometimes, ground-glass attenuation is the sole abnormality suggesting interstitial lung disease and biopsy is required in this setting 10 to differentiate CPFE from other The development of regional airspace disease with scattered areas of radiolucency in a patient with centrilobular emphysema has previously been described in patients with pneumonia and has been termed a "Swiss Cheese" appearance, which describes non-uniformly perforated emphysematous lung tissue amidst dense consolidation.(7-9) However, both the pathophysiology and imaging of Sponge Lung shows Keywords: Emphysema, Goltz syndrome, Lung disease.

While more common types of emphysema impair major airway structures and disrupt normal airflow, paraseptal emphysema is unlikely to cause noticeable breathing problems in its initial stages. 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. The affected lobules are almost always subpleural, and demonstrate small focal lucencies up to 10 mm in size. 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. It can be speculated that pulmonary perfusion deficiency may lead to misbalanced inflammatory response and tissue damage repair, resulting in paraseptal emphysema.
