My 69-year old brother (a smoker) has had chest x-ray. The findings are: Inhomogeneous opacities are noted at the right upper lobe with a suspicious thick-walled lucency. A small ovoid opacity is seen at the left lower lobe superimposed on the 7th left posterior rib. The heart is borderline in size. Aorta is segmentally calcified. Diagram and costophrenic sulci are intact. There is an old fracture at the lateral aspect of the 4th left posterior rib. Small hypertrophrc spurs are noted along the lateral margins of the thoracic bodies. Please tell me what it means. Thank you.
