Hello, I have a question regarding my 3 year old son. About a month ago he was complaining that the right side of his abdomen was hurting a lot. We took him in for testing where they did blood, urine and xray and said he has pneumonia in the right lung towards the bottom which would explain the abdominal pain. However he was not coughing, no fever and even his pediatrician listened with a stethoscope the next day and said he sounds fine. I insisted on another xray which she did and then she appologized that she was wrong, and yes he has pneumonia. So he took amoxicyllin for 10 days, 6g twice daily. 3 weeks later we scheduled a follow up xray since she says that it takes a while to clear up. We did the xray and there was no change whatsoever. So now she says its probably not pneumonia and need to see a pediatric pulmonologist. The pulmonologist looked at all the xrays and says no pneumonia. He recommended a CT scan, whcich we did. Now he says good news, the CT is good, no cancer or anything however the right outer lung has thickened tissue. He says this could be due to a old infection and in any case he is fine. Now my question is is this thickening dangerous, will it pass and is this ok for a three year old. Also, what type of infection could have gone unnoticed by me earlier. I like this doctor, but I am a mom who is very worried about my son. Thank you

Hi, Welcome to this forum. Can understand your concerns. It is good that your child does not have pneumonia or any other things, the child only has pleural ticketing. There are many causes of pleural thickening like bacterial pneumonia, injury to the Chat Doctor. However, since you have already done CT scan and x-ray chest the chances of injury to chest, bacterial pneumonia, pleural effusion are less. There are some diseases like tuberculosis which have a higher chance of pleural technique, the child should be investigated for tuberculosis. I hope this will help you. Take care. Regards
