For lung nodules, air bronchograms used to be associated with infectious causes of consolidation and, therefore to be benign. However, in the setting of a lung nodule, an air bronchogram is actually more frequent in malignant than in benign nodules. [1] [4] studied the tumour-bronchus relationship and described five types: [1]
