CT images of pulmonary aplasia and pneumonectomy. Rudimentary blind-ending bronchus can be seen on axial CT image in a 27-year-old asymptomatic female with pulmonary aplasia and helps in the differentiation from pulmonary agenesis (a) (arrow). 3D reformatted images (b, c) show the only left airways and compensatory hyperplasia of the left lung into the right side. The left main bronchial stump is observed on axial CT and 3D reformatted images in a 33-year-old patient with right pneumonectomy (d–f) (arrows).
