Inflammation-induced frosted glass nodules are cloudy, thin shadows with a frosted glass texture and mildly increased density in the lungs on CT imaging due to a pathologically scaly growth pattern. In inflammation-induced frosted glass nodules, which are abnormally proliferating epithelial cells or well-differentiated tumor cells that grow in a squamous manner, gradual resorption or disappearance of the surrounding tissue can be observed after anti-infective treatment. If the nodule is accompanied by obvious lobulation, vacuoles, pleural depression signs or obvious solid components, does not improve after anti-infective treatment, becomes larger in diameter, or develops nodular changes in the middle, it may be an early stage tumor. The specific features of inflammation-induced ground-glass nodules can be understood by consulting the relevant physician.
