A helpful mnemonic for causes of pulmonary nodules with air bronchograms is:

OBALLS

Mnemonic

OBALLS

O: organising pneumonia
B: bronchoalveolar carcinoma (adenocarcinoma)
A: acute respiratory distress syndrome (ARDS)
L: lymphoma
L: lipoid pneumonia
S: sarcoid osis

Another consideration is Goodpasture syndrome; however, it is arguable that it appears as an air bronchogram within ground glass opacification rather than with a solid nodule.
