Lung infection that cause a mass?

Many: Fungi like candida, blastomyces, coccidioidomycoses or paracocci can all cause infiltrates or processes that look like masses. Tb itself can cause a mass-like effect of tuberculoma and even pneumonia can cause mass like infiltrates and a scar later that involutes to look like a mass. Parasites do too. So we have to rely on symptoms, risks and the work up to make diagnoses.
