Usually, pulmonary emphysema is categorized into three kinds associated to the lobular anatomy: centrilobular emphysema, panlobular emphysema, and paraseptal emphysema.
I have with me here Jessica, a patient who presents with complications which I need to evaluate.
With magnification of the expanded airspace, the enveloping lung parenchyma is compressed, which makes it possible observation of a clear border involving the emphysematous area and the normal lung.
Because the disease grows from the centrilobular portion, normal lung parenchyma in the perilobular portion seems to be preserved, even in instances of far-developed pulmonary emphysema.
In panlobular emphysema, HRCT shows either panlobular low attenuation or ill-defined diffuse low attenuation of the lung.
Paraseptal emphysema is characterized by subpleural Ill-defined cystic spaces.
No university recognized categorization system of these kinds exists, but relationships of autopsy outcomes in 1,823 cases over a 12-year period ascertain that the radiographic and pathologic characteristics of the emphysemas are easily understood if centrilobular, panlobular, paracicatricial, and restricted types of the disease are identified.
Centrilobular emphysema linked to cigarette smoking is the most prevalent type.
Recent articles related to imaging of pulmonary emphysema will also be covered in this paper, cush as morphometry of the airway in cases of chronic obstructive pulmonary disease, including pulmonary fibrosis and pulmonary emphysema, and bronchogenic carcinoma linked to bullous lung disease.
There are several forms of emphysema that should be considered as unique disease entities.
