Table 1 Radiological diagnosis of pneumonia in pediatrics

Lober pneumonia

Non-segmental, homogenous consolidation predominantly involving one lobe with air bronchograms (large bronchi remain patent and air filled in contrast to the adjacent non-aerated lung

Bronchopneumonia

Mild disease can manifest as peribronchial thickening and poorly defined air-space opacities; inhomogeneous patchy areas of consolidation involving several lobes reflect more severe disease

Interstitial pneumonia

Oedema and cellular infiltrates predominantly involving the interstitial tissue of the alveolar septa and surrounding small airways and vessels
