Ground Glass Opacities on Lung CT - Pathophysiology Ground glass opacity lung is denser (whiter) than normal lung, but as compared to consolidation, not dense enough to obscure vessels within the area of GGO. Most often, GGO is caused by the partial replacement of air within alveoli with something that normally does not belong there. Unfortunately, there are many things that can partially fill alveoli, so the finding is non-specific. History, physical exam and other findings are key!
