29 Panacinar Emphysema - Radiology Key
Jan 14, 2016 · Panacinar (syn. panlobular) emphysema affects each acinus in its entirety and all acini within the secondary pulmonary lobule (Fig. 29.2, right). It is the characteristic finding in patients with α-1-antiprotease deficiency. While panacinar emphysema may involve the lung diffusely, predominant lower lung involvement is characteristic.
