i am concerned about an xray result. I had to have a ct scan to determine more. the xray report said, There are some ill-defined patchy, mixed air space and interstitial opacities seen in the left perihilar region, notably adjoing the left upper lobe pulmonary artery. No focal consolidation is seen. The remaining lungs are clear, as are the pleural spaces. No bony abnormality is seen. What does this mean. I have had whooping cough just recently, would this have anything to do with it.
