Fibrous cord shadows in the lungs are imaging signs that usually represent old lesions, indicating shadows from previous infections with pneumonia or cured tuberculosis.
Fibrotic streaks in the lungs are commonly seen in X-ray chest radiographs or CT chest examinations, often suggesting that fibrotic streaks are seen in the lungs as old foci. These foci usually do not have any clinical symptoms, so they do not need to be treated with any special medication, but it is important to pay attention to regular follow-up to observe whether the foci are changing or not.
In addition, a small number of patients with fibrous streaks in the lungs may have coughing symptoms, usually mainly irritating dry cough, and should consult a doctor promptly for treatment if the above symptoms occur.
