Both these radiographs showed pneumonic consolidation. In the first radiograph, the consolidation is at the right upper zone with its lower margin limited by the right horizontal fissure. The consolidation is fairly homogenous. In addition, the right costo-phrenic angle is blunted indicating small amount of effusion. This pneumonia is most likely bacterial in origin.
In the second radiograph, the consolidation is at the left upper zone. It is characterised by multiple cavitations. This pneumonia is most likely tuberculous in origin.
