Overview
On chest Xray Alpha1-antitrypsin deficiency (AATD) emphysema presents as a hyperlucent appearance because healthy tissue has been destroyed.Affected regions also are described as oligemic because they lack the normal rich pattern of branching blood vessels.An unusual characteristic in alpha1-antitrypsin deficiency is found in about two thirds of PiZZ patients; the emphysema has a striking basilar distribution.In contrast, cigarette smoking is associated with more severe apical disease.
X Ray
On chest Xray Alpha1-antitrypsin deficiency (AATD) emphysema presents as:[1][2]
- a hyperlucent appearance because healthy tissue has been destroyed.
- Affected regions also are described as oligemic because they lack the normal rich pattern of branching blood vessels.
- An unusual characteristic in alpha1-antitrypsin deficiency is found in about two thirds of PiZZ patients; the emphysema has a striking basilar distribution.
- In contrast, cigarette smoking is associated with more severe apical disease.
