Intrapulmonary striae refers to the high density shadow of striae detected by chest X-ray, CT and other imaging examinations, which is often an old lesion.
Intrapulmonary striae are the result of lesions being replaced by fibrous tissue during the repair process. They are chronic stable lesions, similar to old skin scars, and are commonly seen in patients with previous tuberculosis, long-term heavy smoking, and workers in dusty environments, etc. The presence of these lesions alone does not have a clear clinical significance, and the presence of lung disease is often accompanied by other imaging signs.
The presence of intrapulmonary striae generally does not affect lung function and does not require medication, but patients need to quit smoking, avoid dust and haze pollution, and follow up with regular lung imaging tests.
Therefore, it is recommended that patients combine symptoms and other tests to make a comprehensive judgment, and regular follow-up observation.
