New groundglass opacity found
In my annual lung CT scan today, they found a new 11.9 x 26.1 x 15.2 mm region of ground glass opacity laterally in the right middle lobe which may be "postinflammatory", according to them.
What does the new finding indicate in terms of cause, characteristics, prognosis, and treatment? Is this potentially a serious condition? I'm a 70 year old diabetic who takes insulin. They have asked me to repeat the test in 6 months.
