Ground-glass opacity on chest computed tomography most commonly indicates which finding?

Ground-glass opacity on chest CT means hazy increased attenuation where the underlying vessels and bronchial markings remain visible. This pattern reflects partial air-space filling or mild interstitial thickening, so the air in the lungs is being displaced but not completely replaced. That’s why the finding most often points to processes that partially fill the air spaces or inflame the interstitial tissue—such as pneumonia, pulmonary edema, or other inflammatory/interstitial conditions. It isn’t a complete consolidation (which would obscure the vessels), it isn’t a normal scan, and it isn’t hyperinflation (which would look more lucent with expanded air spaces).
