A few fibrous foci in both lungs, a form of repair of a lung lesion, is a sign that the lesion is getting better, and is commonly seen after pneumonia, tuberculosis, and other lesions, as well as in lung tumors. A small fibrous foci in both lungs refers to the presence of a small number of striated shadows in the lungs on CT when patients undergo lung imaging. This kind of shadow is usually unaffected by the body, does not interfere with normal respiratory function, and usually does not require treatment. However, when the CT imaging examination concludes that the patient has lung inflammation, and the scope of the pulmonary fibrous foci gradually becomes larger, and there is a decline in lung function, it is necessary to give the correct method of treatment in a timely manner under the advice of the doctor. It is necessary to follow the doctor’s advice to actively use antibiotic drugs such as cephradine and amoxicillin to control the development of inflammation and avoid the increase of pulmonary fibrous foci. To summarize, patients are advised to go to the hospital in time for examination to avoid delaying the condition. Drugs need to be used under the guidance of doctors, avoid self-medication.
