Inflammatory changes in the lungs are a description of a pathology found through imaging such as X-rays and CT of both lungs. Clinically, it is more common to have pathogens invade the lungs and cause inflammatory reactions in the lung tissue: first, they are seen in bacteria, viruses, mycoplasma, chlamydia, rickettsia, and SARS coronavirus. Secondly, there are also physicochemical factors that cause inflammation in the lungs, such as invasion of allergens such as radioactive rays, pollen, cold air, sulfur dioxide, ammonia, and various causes and idiopathic interstitial fibrosis of the lungs appearing as non-infectious inflammatory changes. Symptomatic and etiologic treatment is usually required, and CT or MRI of the lungs can be reviewed to clarify whether the inflammation is a calcified, fibrotic change left after healing and does not require special treatment. If the inflammation belongs to the active stage, timely treatment is needed.
