I'm trying to understand the results of my CT scan. It mentions a "small calcified nodular opacity" in the right middle lobe, which apparently measures 3.7 mm and might be a healed granulomatous lesion. There are also "few subcentimeter sized noncalcified lymph nodes," with the largest one being 9.1 mm in the AP window region. Could you explain what this means and what steps I should take next? I'm a bit worried about these findings.
