In one investigation, 26 (22%) of patients with pneumonia had a completely normal chest examination, whereas abnormal vital signs (temperature >37.0 C; pulse rate >100 beats/min, or respiratory rate >20 breaths/min) were 97% sensitive for the diagnosis of pneumonia [34].

It is something of a misnomer as it actually represents the loss of a normal silhouette. Bronchopneumonia appears on a chest X-ray as bilateral patchy shadows and typically predominates at the lung bases: Lobar pneumonias have specific appearances, which can be explained by the anatomical relationships of the lobes of the lung to their surrounding structures. Similarly, the more recent European guideline does not recommend a routine chest radiograph in the community setting but indicates that it could be done in cases in whom, despite c-reactive protein (CRP) testing, there is persistent doubt as to whether the diagnosis is pneumonia or another respiratory tract infection, and also in patients with suspected aspiration pneumonia [11].
