Ground-Glass Opacity

Ground-glass opacity (GGO) refers to a hazy area seen on a lung imaging scan (like a CT scan) that appears cloudy but doesn't obscure the underlying structures completely. It indicates partial filling of air spaces or thickening of tissue in the lungs, often caused by inflammation, infection, or other lung conditions. While sometimes temporary and benign, GGO can also be associated with more serious issues like tumors or early signs of lung disease. Further medical evaluation is needed to determine the exact cause and appropriate treatment.
