My father is 60 years old. Since last few days, he was having problem in breathing, specially in nights. So he want to doctor and took medicines, Ct scan also done. Let me paste report points here. 1. B/l ling fields shows normal air attenuation with few bronchovascular markings. 2. Bilateral bronchovasculature is otherwise normal. 3. Tracheobronchial tree is normal. Trachea slightly on right side. 4. Mediastinal shadows are within normal limits. Great vessels are normally opacified. 5. Oesophagus is collapsed and normal. 6. Cardiac silhouette is normal. 7. Bilateral pleural cavities are clear and chest wall is within normal limits. 8. No evidence of any lytic lesion seen in the vertebrae. Please can you explain these.
