Postoperative ground glass shadows that become streaks of hyperdense shadows are usually associated with postoperative infection inflammation or scar formation. If improper care is taken after glass grinding surgery in the lung, resulting in infection at the incision, causing local inflammatory reaction and inflammatory exudation, it will be found that the glass shadow becomes streaky and hyperdense at the examination. Glass grinding surgery requires removal of diseased lung tissue, and scarring of the lung tissue at the incision site forms after healing, which will also show streaks of high-density shadows in the imaging examination. If the streaky hyperdense shadow is detected, it is recommended to review the CT and MRI of the lungs regularly; patients who are worried about malignant lesions can be diagnosed and analyzed by pathological biopsy, and once the diagnosis is confirmed, the treatment should be carried out immediately in order to avoid delaying the condition.
