Chest xray

My husband recently had an xray and cat scan (waiting for ct results).  The xray findings said: lungs appear normally aerated.  There is biapical pleural thickening with right apical blebs and bullae.  The heart is normal in size.  The right hilum is mildly prominent.  There is no lung infiltrate, vascular congestion or pleural disease.  The bony thoax appears unremarkable.  The Impression says: Right apical pleural thickening and apical bullous changes, which may be secondary to prior inflammatory process.  Otherwise no acute cardiac or pulmonic process seen.  Can you explain this?

Basically it says that your husband’s lungs are normal, except for some thickening in the top portion of his lungs with small cyst formation in the top portion of his right lung.  These abnormal findings are common, thought to be due to an infection, often in the distant past, and usually deemed to be of no consequence to his health.
