Multiple nodular high-density shadows in both lungs partially calcified, which indicates that the nodules have appeared for a long time, and the condition is relatively stable, including inflammatory lung nodules, tuberculous lung nodules and non-infectious benign lesions causing lung nodules. 1. Inflammatory pulmonary nodules: Inflammatory pulmonary nodules are caused by bacterial and fungal infections that lead to pulmonary nodules, which are treated with cephalosporins, penicillins or fluconazole. 2. Tuberculous pulmonary nodules: tuberculous pulmonary nodules using rifampicin isoniazid for anti-tuberculosis treatment, need to pay attention to blood tests to check liver function, because anti-tuberculosis drugs will affect liver function. 3. Non-infectious benign lesions: for example, idiopathic diffuse interstitial fibrosis of the lungs can cause calcification of high-density nodules in the lungs. Patients usually have discomfort, timely to the hospital for examination, and actively cooperate with the doctor’s treatment, do not be careless, so as not to delay the treatment, affecting the therapeutic effect.
