Preferred Label :
panacinar emphysema; Definition :
Pathology.—Panacinar emphysema involves all portions of the acinus and secondary pulmonary
lobule more or less uniformly (42). It predominates in the lower lobes and is the
form of emphysema associated with α1-antitrypsin deficiency. CT scans.—Panacinar emphysema
manifests as a generalized decrease of the lung parenchyma with a decrease in the
caliber of blood vessels in the affected lung (97,98) (Fig 46). Severe panacinar emphysema
may coexist and merge with severe centrilobular emphysema. The appearance of featureless
decreased attenuation may be indistinguishable from severe constrictive obliterative
bronchiolitis (99). The term panlobular emphysema is synonymous. (See also emphysema.)
