Cystic (Bubbly) Lucencies in Adenocarcinoma. CT scan at lung
windows through the tracheal carina shows a thin-walled irregular lesion
with cystic lucencies (arrow) in the anterior segment of the right upper
lobe. Note the presence of smoking-related respiratory bronchiolitis seen
as upper lobe ground-glass opacity. PET scan (not shown) showed
increased activity within the lesion. Resection revealed adenocarcinoma.
