Increased lung texture in children is a result of a chest radiograph and usually indicates the presence of tracheitis or bronchiectasis. A normal chest radiograph report will not show an increase or decrease in lung texture. If the inflammation is more extensive, the texture of tracheitis and bronchitis will become thicker and can be seen on the chest radiograph. If children have recurrent cough and sputum, they can be treated with medication under the guidance of a doctor. If the symptoms do not improve for a long time, X-rays are usually taken to determine if there is a lung infection. In addition, the child will be given blood tests and mycoplasma antigens to clarify the cause of tracheitis or bronchitis that is causing the thickened lung texture. If it is caused by a bacterial, viral, or mycoplasma infection, the cause can be clarified and then targeted treatment can be administered. If the increased lung texture is caused by a viral infection, antiviral medications, such as Blue Scutellaria Oral Liquid, can be taken under the guidance of a doctor. If the increase in lung texture is caused by bacterial infection, antibiotics can be taken under the guidance of the doctor for treatment. If the increased lung texture is caused by mycoplasma infection, it can be treated with oral azithromycin and cephalosporins. If the symptoms are severe, intravenous fluids may be an appropriate choice. If cough and sputum cannot be relieved, oral treatment with bromohexine tablets and powerful phlegm is recommended.
