This is a similar question a friend of mine asked recently. What I told her was that "possible" also means that there's a good chance that it's just the pneumonia, but the interpreting doctor isn't 100% certain. It's basically doctor language for, "You should probably have this patient have a repeat x-ray at some point in the future." It's also good that interpreting doctors communicate this way, because, if you do have something other than just pneumonia, you'll definitely want an early diagnosis and proper treatment for that too. In my friend's case, it turned out to be just pneumonia and a future x-ray showed up normal. So, I think the best thing for you to do here is to keep in touch with your physician. Plus, please keep in mind that, when it comes to your healthcare, you are the boss. If you have questions, you can always call your doctor for clarification. Hope this helps. John. Site Moderator.
