Lung ct with hyperdense shadow means that when ct examination is performed, this imaging manifestation is a local lesion with a higher density than normal body tissues, which may be caused by inflammation, calcified foci, tumors and other factors.
Normal lungs are hypodense shadows on imaging, and the presence of increased density shadows on ct examination of the lungs can be caused by a variety of etiologic factors. Some inflammatory lesions will show flaky, cloudy hyperdense shadows, such as pneumonia. In the case of calcified foci, they tend to appear as rounded hyperdense shadows.
Benign tumors tend to show popcorn-like hyperdense shadows, such as misshapen tumors. And malignant tumors, due to the proliferation of local tumor cells, mostly show irregular hyperdense shadows, such as lung sarcoma, lung cancer and other diseases.
Therefore, when the ct examination of the lung is found to have increased density shadow, the relevant examination should be further improved to find out the cause of the disease, and treatment should be carried out if necessary.
