[|Human|] My son has been sick for sometime w/soar throat(cleared up), but still has Upper respiratory congestion. He had x-ray today and outcome was opaques spots on lung. Gave him anti antibiotics and told him to come back in 3 weeks for follow-up x-ray. What does it mean to have opaque spots? Thank u Karan Paulson
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Opaque spot on chest x-ray is commonly due to lung infection like pneumonia or tuberculosis and lung cancer. Since patient is young, no need to worry about lung cancer. He is also having recent history of upper respiratory tract infection (URI). This can cause pneumonia in some pediatric patients. So opaque spot is mostly due to pneumonia. And this is why doctor has given antibiotics and ask four repeat chest x-ray after 3 weeks to see improvement in chest x-ray. So give your son antibiotics as per doctor s advice and get done chest x-ray after 3 weeks. Don't worry, he will be alright. Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks.
