Inflammation of the lungs can develop masses in specific cases, such as septic bacterial infections, such as Staphylococcus aureus, Klebsiella, Pseudomonas aeruginosa, and Mycobacterium tuberculosis, which tend to make the inflammation of the lungs chronic and relatively long-lasting, causing damage to the mucosa of the lungs and the formation of inflammatory masses with manifestations of fibrosis and calcification, as well as the formation of masses, also known as inflammatory pseudotumors. After the standardized and sensitive anti-inflammatory treatment, even if the cure is completely achieved, the lungs may be left with varying degrees of old fibrotic and calcified lesions, forming inflammatory residual scars that manifest as masses.
