<s>[INST] what does this sentence mean on my post surgical chest x-ray:  Interval resolution of the right-sided pneumothorax and chest wall subcutaneous emphysema. I am 59, white female, 2 months post-op after right middle lobectomy and removal of calcified lymph nodes. [/INST] Thanks for your question on Healthcare Magic. I can understand your concern. You are having right middle lobectomy, means your middle lobe of right lung has been removed. After such debulking surgery, there is empty space remained in the chest cavity. This empty space is gradually obliterated by hyperinflation of other lobes (upper and lower lobes). This process takes almost 6-8 months. Since it's only 2 months post operatively, we should rule expect some amount of resorption of empty space. So radiologist use term 'interval resolution' as it is not completely resolved. So don't worry, this space will fully resolve in 6-8 months. Get done regular follow up with chest x ray. Hope I have solved your query. I will be happy to help you further. Wish you good health.Thanks. </s>
