Welcome to icliniq.com.
It would be better if I had the opportunity to see your prior X-ray to compare with the most recent one. Your previous X-ray (attachment removed to protect the patient's identity) shows :
1. Upper normal size cardiomediastinal silhouette.
2. Prominence of the pulmonary vasculature.
3. Presence of bibasal airspace opacities likely atelectasis (hypoventilated lung parenchyma).
4. No convincing evidence of pleural effusion and pneumothorax.
5. Bones are unremarkable.
I do not see any findings to suggest COVID (coronavirus disease) pneumonia. It would be great if you can upload the prior X-rays.
