What is the disease of flocculent shadow in the lungs?

With the improvement of people's living standards, more and more people have begun to pay attention to health preservation. Many companies will also conduct regular physical examinations for employees. However, there are many items in the physical examination, such as chest X-ray examination and CT examination, etc. Through this examination method, you can directly understand the chest condition, but some people will have examination results of flocculent shadows in the lungs. So what is the disease of flocculent shadows in the lungs?

First, what disease is the flocculent shadow in the lungs ? 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. The most common pathogenic microorganisms are bacteria. The shadows often appear in flakes on chest X-rays. In severe cases, the entire lung lobe may be affected. A routine blood test can reveal a significantly increased white blood cell count. After anti-inflammatory treatment with antibiotics, a review of the chest X-ray can reveal that the lung shadows have been significantly reduced or even completely disappeared. Generally, the patient will recover after 2 weeks of treatment.

Second, pulmonary 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." Patients often have symptoms of tuberculosis poisoning such as coughing, sputum, hemoptysis, low-grade fever in the afternoon, fatigue, night sweats, and loss of appetite. If acid-fast bacilli are found in the sputum and the skin tuberculin test is strongly positive, the diagnosis can usually be confirmed. Most patients with pulmonary tuberculosis respond well to treatment with anti-tuberculosis drugs (remifen, levofloxacin, ethambutol, etc.), but if the spherical tuberculosis lesions are combined with cavities, or if there is "damaged lung", they should undergo thoracic surgery for resection.

What disease is the flocculent shadow in the lungs ? Pulmonary aspergillosis: It is a fungal infection of the lungs, also known as the saprophytic Aspergillus fumigatus infection, which manifests as isolated or multiple spherical lesions in the lungs with typical "crescent-like translucent areas" inside. As the body position changes, the position of the crescent-like translucent areas also changes. Most patients have no systemic symptoms, but a few may have hemoptysis and cough. The best treatment is surgical resection.
