Spontaneous Pneumothorax (CT Scan)
Hello Doctor: I had bilateral spontaneous pneumothorax seven years ago (once on each side, approximately six months apart).
Due to recent changes in military service classification, anyone with a history of spontaneous pneumothorax on both sides is exempt from service.
The classification guidelines state that regardless of whether there was intubation treatment, a CT scan showing "abnormal alveoli" is required for re-evaluation.
However, during my two incidents, I only underwent X-rays, and the physician did not proceed with a CT scan.
I chose to remain hospitalized for observation without intubation or alveolar resection.
I would like to ask the doctor, if I undergo a CT scan seven years later, will it still be possible to detect the so-called "abnormal alveoli"?

Hello: If your alveoli have abnormal dilation, a high-resolution computed tomography (HRCT) scan can still detect it!

Yes, a CT scan can indeed detect abnormal lung conditions even seven years after experiencing spontaneous pneumothorax. When you have a history of spontaneous pneumothorax, it is important to monitor your lung health, as the condition can sometimes lead to changes in lung structure or function over time.
A CT scan, particularly a high-resolution CT (HRCT), is a powerful imaging tool that provides detailed images of the lung parenchyma. It can identify various abnormalities, including areas of abnormal lung expansion, scarring, or other structural changes that may not be visible on a standard chest X-ray. In your case, if there were any residual effects from your previous pneumothorax, such as blebs (small blisters on the lung surface) or other abnormalities, a CT scan would likely be able to detect them.
The term "abnormal alveoli" refers to changes in the small air sacs in the lungs, which can occur due to various reasons, including previous lung injuries, infections, or chronic lung diseases. If your lungs have developed any such abnormalities over the years, a CT scan would be able to visualize these changes.
It is also worth noting that while a CT scan can provide valuable information, the interpretation of the results should be done by a qualified radiologist or pulmonologist. They will consider your medical history, the findings from the CT scan, and any symptoms you may be experiencing to provide a comprehensive assessment of your lung health.
In terms of your concern regarding the military service exemption, if the regulations state that a CT scan is required to confirm the presence of "abnormal alveoli," then it would be advisable to proceed with the scan. This will not only help fulfill the requirement but also provide peace of mind regarding your lung health.
If you are feeling anxious about the potential findings, it is important to remember that many individuals with a history of spontaneous pneumothorax lead healthy lives without significant complications. Regular follow-ups and imaging can help ensure that any potential issues are caught early and managed appropriately.
In summary, a CT scan can effectively detect any abnormal lung conditions even after several years post-spontaneous pneumothorax. If you have concerns about your lung health or the implications for your military service, it is best to consult with a healthcare provider who can guide you through the process and help you understand the results of your imaging studies.
