Pulmonary inflammatory nodules are benign nodules, generally small in size, mostly ground glass-like changes, no clinical symptoms do not require special treatment, dynamic follow-up chest high-resolution CT, once a year can be. Pulmonary inflammatory nodules are also seen in people with long-term smoking and exposure to dust, including masons, coal miners, chefs, hairdressers, etc. Long-term exposure to odor stimulation can easily form inflammatory nodules. Inflammatory nodules are small in size and scattered in distribution and are not associated with early cancerous changes such as short burrs, lobulation, pleural traction signs, or pleural indentation. If clinical symptoms are present, anti-inflammatory and anti-infective treatment can be given. It is possible that the nodules may become smaller on review of chest imaging, but it is important not to take it lightly. If the nodule is growing, especially with short burrs, lobar shape, or larger than 8mm, we should be alert to whether the inflammatory nodule is early lung cancer, closely observe the changes of the nodule, and if necessary, provide enhanced CT examination of the chest to assess the possibility of lung cancer as early as possible.
