I'm a bit worried about my recent CT report, and I could really use some guidance. It mentions that there's a collapse consolidation in my left lower lobe and some specks of calcification with fibronodular changes. They also found a few confluent nodules and scattered small nodules in both lung fields, plus ground glass opacity in my right lower lobe. The impression notes something about mediastinal lymphadenopathy and a mild pleural infusion on the left. Can someone explain what all these terms mean and what I should be concerned about? Is this indicative of a serious condition or something treatable?
