What is the difference between limited emphysema and emphysema?

Patient's question:

Recently, I've been experiencing chest pain and tightness in my chest. The hospital examination indicated a respiratory disease, but the medication hasn't been very effective. Recently, my cough has worsened. Could you please explain the difference between localized emphysema and emphysema?

Doctor's answer:

The so-called localized emphysema is distinguished from diffuse emphysema. If emphysema is confined to a single lung lobe or segment, it is referred to as localized emphysema. In this case, it will never cause obvious shortness of breath or other related symptoms. However, in some cases, it is necessary to completely eliminate the specific cause of recurring symptoms similar to emphysema. Otherwise, the condition may worsen.
