Postanterior (A) and lateral (B) chest radiographs show areas of consolidation and several air-fluid levels within the right lower lobe. Less extensive consolidation is evident in the right middle lobe. Computed tomography (CT) image (C) confirms the radiographic findings and also demonstrates a few centrilobular nodules in the right middle lobe (arrow). The patient was a 50-year-old man with pneumonia due to anaerobic organisms.
