Striated hyperdense shadows in the lingual segment of the upper lobe of the left lung may be related to scars left after the healing of pneumonia, tuberculosis and other diseases. Striated hyperdense shadows in the lingual segment of the upper lobe of the left lung can usually be found during imaging tests, such as chest CT. The lingual segment of the upper lobe can not be accurately observed on normal chest radiographs, but it can be observed on CT, and striated changes have occurred in this area, which may be the fibrotic scars left behind after the healing of diseases such as pneumonia or tuberculosis. Generally speaking, if there are no uncomfortable symptoms, there is no need for special treatment, and you can go to the hospital regularly for review. If you have symptoms, you should seek medical advice and treatment under the guidance of your doctor.
