Pneumonic nodules usually do not continue to grow. Pneumonic nodules are usually caused by pneumonia, tuberculosis and other inflammatory diseases after long-term infiltration and infection. Pneumonic nodules can be gradually absorbed, reduced or even dissipated through anti-inflammatory and nebulizing treatments; some infected nodules may leave scarring on the lungs after anti-inflammatory treatment, which may not dissipate easily. The nodule is usually stable and rarely grows or grows slowly to form an inflammatory pseudotumor. It is recommended that lung nodules be reviewed regularly, and if a nodule appears on the lung and grows rapidly, it is recommended that the patient go to the hospital in time to rule out neoplastic disease.
