What is the high density shadow of lung?

The concept of lung hyperdensity is too broad. It may be seen in many cases. For example, calcification in the lung may be manifested as hyperdensity shadow in the lung, even close to bone density. This condition mostly represents benign lesions. There are also some malignant tumors in the lung, which may be accompanied by scattered calcification points in the lesion. This situation should also be vigilant. There are also benign tumors in the lung, which may also be accompanied by calcification within the lesion. For example, hamartoma may be accompanied by popcorn calcification, and patchy hyperdensity in the lungs may represent inflammation. For example, pneumonia, tuberculosis and other related conditions may also be atelectasis, or even pulmonary infarction. In cases related to pneumonic lung cancer, granular hyperdensity is likely to appear as nodular or reticular hyperdensity or fibrous striations, which also need to be analyzed in conjunction with the patient's specific condition. Hyperdensity in the lungs is likely to be a mass, and even associated with shadows, spicules, pleural traction, etc. These are the conditions that need to be vigilant for lung cancer.
