Most of the lung flaky hyperdense foci are inflammatory exudation and edema caused by lung infection, tuberculosis or immune system diseases, or fibrous scar foci left after healing of the disease, and a small portion of them are lung atelectasis caused by central lung cancer.
1. Lung infection: such as pneumonia, bronchial dilatation, pulmonary aspergillosis and other diseases causing inflammatory infiltration and edema, which can be manifested as flaky high-density foci in lung lobes in imaging examination.
2. Tuberculosis: Mycobacterium tuberculosis infection can cause tuberculosis, which may also show flaky high-density foci on imaging.
3. Immune system diseases: rheumatic pneumonia and connective tissue disease can also cause inflammatory reaction and edema in lung tissue, which can be manifested as flaky hyperdense foci.
4. Centralized lung cancer: centralized lung cancer can compress or block the lung bronchial tubes and cause pulmonary atelectasis, which is manifested as flaky hyperdense foci.
It is suggested that if you have symptoms of lungs with flaky high-density foci, you need to have further examination to find out the cause and then treat under doctor’s guidance.
