However, since this approach would miss 5% of pneumonias, they recommend that this should be reserved only for cases with reliable follow up and also a low likelihood of morbidity if pneumonia was missed [29]. Part of the reason for these observations may be the inaccuracy of clinical examination with considerable interobserver variation in the recording of symptoms and also a high degree of interobserver error in the physical examination of the chest [1, 25, 32]. Lobar collapse can be caused by a number of entities as detailed in the diagram below: Once the airway is completely occluded, trapped air distal to the obstruction is absorbed into the surrounding tissues collapsing the alveoli as it does so.

The consolidation obscures the left heart border indicating it is in the adjacent lingula of the left upper lobe. For these reasons it is widely recommended that routine radiology be performed in any patient suspected on any clinical grounds of having CAP. Community-acquired pneumonia (CAP) remains a common condition associated with considerable morbidity and mortality. Springer Nature. Researchers reported that CAP patients with initially normal chest x-rays were more likely to have viral (H1N1) pneumonia compared to those with abnormal radiography and to be earlier in the disease progression. If the X-ray images show abnormalities, this means that there is something unusual on the image of the chest. However, the British Thoracic Society guideline indicates that while all patients admitted to hospital with suspected CAP need a chest radiograph, in the community it is unnecessary for a chest radiograph to be done unless the diagnosis is in doubt, or clinical progress is not being made on treatment of a patient with suspected CAP, or if the patient is likely to have an underlying pathology, such as lung cancer [7]. : European Respiratory Society; 2014. p. 4263.
