Radiographic findings (plain film A): The lung volume appears normal. Linear densities and cystic spaces tend to spare the lung base. A few ill-defined nodules appear in the mid zones. Vessels and bones appear normal.


A CT scan (B and C) was performed to define the cystic changes. Multiple cysts of various sizes are present. They have thick walls, in contrast to the thin walls that are expected in emphysema.


Near the base, early lesions are present. There are tiny cysts with thick walls, some of which abut the pleura (R). A small, subpleural nodule is present posteriorly on the left.
