Interstitial lesions can usually be seen on radiographs in children. However, the specific diagnosis of interstitial pneumonia requires a combination of clinical symptoms and signs. Interstitial pneumonitis can be seen as ground-glass shadows or certain lattice-like changes on lung imaging, and the severity of lung inflammation can be seen on chest X-ray. However, if the diagnosis of interstitial pneumonitis is needed, it should be combined with clinical symptoms, physical signs, chest CT examination and other related tests to assist in the diagnosis. If the lesions appear cough, shortness of breath and other respiratory manifestations, and the chest X-ray suggests interstitial inflammation of the lungs, you need to follow the doctor’s instructions for treatment, and also need to maintain air circulation and pay attention to hygiene in general.
