What disease could it be if there is a shadow on the lung?

Once a disease occurs in the lungs, it will directly affect the body's respiratory function, and in severe cases it will threaten the patient's life safety, so everyone must pay attention to it and actively check it after discovering the problem. The most accurate way to check now is CT, but some patients' test results will show shadows on their lungs, which makes patients very worried. So what disease is the shadow on the lungs?

First, what disease would the shadow on the lungs cause? Lung infection. These mainly include pneumonia, tuberculosis, bronchiectasis, pulmonary fibrosis, interstitial pneumonia and pulmonary aspergillosis. In addition to lung shadows on X-ray examinations, these diseases are often accompanied by other symptoms, and it is not difficult to make a clear diagnosis clinically.

Second, what disease would the shadow on the lungs cause? Pneumonia. It is a lung infection caused by pathogenic microorganisms (bacteria, mycoplasma, chlamydia, viruses, etc.). In addition to lung shadows on X-ray examinations, patients also have symptoms such as cough, sputum, fever, chest tightness, fatigue, and difficulty breathing. In severe cases, infectious toxic shock may even occur.

Third, tuberculosis. It is a lung infection caused by a special bacterium, Mycobacterium tuberculosis, and its incidence has been increasing in recent years. Common locations are the apex, posterior segment of the upper lung and dorsal segment of the lower lobe on both sides. The shadows appear as scattered flakes, which may contain calcification foci, sometimes spherical lesions or miliary lesions. In rare cases, the entire lobe of one lung may be affected, forming a so-called "destroyed lung."

What disease might cause a shadow on the lungs? Bronchiectasis. It is a structural change caused by irreversible damage to the bronchus due to external forces. Symptoms usually include coughing, difficulty breathing, and coughing up blood, and it is also a relatively dangerous disease. Aspergillus pulmonary. This is an inhalation infection with symptoms and examination similar to non-tuberculosis, but it can be distinguished from blood tests, and the lesions have a unique structure in the lungs and can be effectively treated with antibiotics.
