Brief Answer:
Detail follows

Detailed Answer:
Dear Friend.
Dry cough that you are having can be because of Lisinopril.
Since you don't have symptoms then the opacities might be benign and not significant. Sometimes its also breast shadow.
To comment further I would like to see your xray.
In case its doubtful , CECT Chest would be done with other blood investigations.
But decision would be taken after visualizing your X ray film.
Please review with me once you have your chest xray for a better comment.
If you have any further query please ask me.
Stay Healthy.
