Typical thin-section CT finding of focal BAC showing “pure GGA” appearance, in which vessels can be seen. GGA was defined as a hazy increased attenuation of the lung without obscuration of the underlying vascular marking. (BAC = bronchioloalveolar carcinoma; CT = computed tomography; GGA = ground-glass attenuation.)

Management schedule after detection of pure GGA lesion. When a round-shaped GGA without central scar formation was detected on thin-section CT as shown in Figure 1, repeat CT was performed 3 mo later on suspicion of focal BAC. If the tumor size had increased or was unchanged, surgery was planned because of the high probability of BAC. (BAC = bronchioloalveolar carcinoma; CT = computed tomography; GGA = ground-glass attenuation.)
