paraseptal emphysema; Definition :
Pathology.—Paraseptal emphysema is characterized by predominant involvement of the
distal alveoli and their ducts and sacs. It is characteristically bounded by any pleural
surface and the interlobular septa (42,43). CT scans.—This emphysema is characterized
by subpleural and peribronchovascular regions of low attenuation separated by intact
interlobular septa (Fig 47), sometimes associated with bullae. The term distal acinar
emphysema is synonymous. (See also emphysema.) [Fleischner Society]; Image(s) :
