Ground-glass opacity is nonspecific, but highly significant finding since 60-80% of patients with ground-glass opacity on HRCT have an active and potentially treatable lung disease.
In the other 20-40% of the cases the lung disease is not treatable and the ground-glass pattern is the result of fibrosis.
In those cases there are usually associated HRCT findings of fibrosis, such as traction bronchiectasis and honeycombing.
On the left two cases with GGO, one without fibrosis and potentially treatable and the other with traction bronchiectasis indicating fibrosis. #Clinical #Radiology #CTChest #GroundGlass #GGO #RadiologyAssistant
