What disease does lung shadow mean

Lung shadows must not be ignored, as they may be caused by lung lesions. Many people do not know what lung shadows mean, and this may be closely related to the disease. Generally speaking, the more serious possibility is lung shadows caused by lung tumors.

1. Lung tumors: mainly include primary lung cancer, secondary lung cancer, inflammatory pseudotumor, etc. Among them, primary lung cancer is the main cause of mental tension in patients with "lung shadows" and is more common in middle-aged and elderly people; secondary lung cancer is caused by the metastasis of malignant tumors in other parts of the body such as the kidneys, liver, and ovaries to the lungs, and its cause is relatively clear; and most patients with inflammatory pseudotumor have a history of pneumonia, which is sometimes difficult to distinguish from lung cancer. A puncture biopsy under CT positioning can make a clear diagnosis. If it can be confirmed as an inflammatory pseudotumor, no treatment is required.

2. Congenital pulmonary dysplasia: including lung cysts, pulmonary hamartomas and pulmonary sequestration, among which lung cysts are more common in male children and young adults; pulmonary hamartomas have a typical image of "popcorn-like"; pulmonary sequestration is a congenital pulmonary dysplasia, which is divided into intralobar and extralobar types. The shadows are mostly located in the posterior segment of the lower lobe.

3. Lung shadows can be benign or malignant . Generally, those over 40 years old are more likely to have malignant shadows, while those under 35 years old are more likely to have benign lesions. Commonly used examinations for lung shadows or masses are divided into imaging examinations (such as chest X-rays, chest CT or MR (magnetic resonance imaging), PET examinations, etc.) and pathological examinations. Among them: imaging examinations can determine the location, size, number and shape of the mass; pathological examinations can determine whether it is benign or malignant. In addition, fiberoptic bronchoscopy is often performed clinically for patients with "lung shadows". This examination can not only understand the location, shape, and relationship of the tumor to the trachea and bronchi, but also perform a biopsy to determine whether it is benign or malignant.
