Aspiration pneumonia most often develops due to micro-aspiration of saliva, or bacteria carried on food and liquids, in combination with impaired host immune function. [30] Chronic inflammation of the lungs is a key feature in aspiration pneumonia in elderly nursing home residents and presents as a sporadic fever (one day per week for several ...
Chest X-rays can be useful in the diagnosis of aspiration pneumonia but may be negative early in the course. [12] Chest CT Scan can identify the presence of a pneumonia as well, and can also assist in characterizing abscesses, foreign objects, or pleural disease. Aspiration seen on barium swallow study.
In some cases, chest CT can reveal pneumonia not seen on x-rays. However, congestive heart failure or other types of lung damage can mimic CAP on x-ray. [15] When signs of pneumonia are discovered during evaluation, chest X-rays and examination of the blood and sputum for infectious microorganisms may be done to support a diagnosis of CAP.
A chest X-ray showing right sided (seen on the left of the picture) pulmonary contusion associated with rib fractures and subcutaneous emphysema. Chest X-ray is the most common method used for diagnosis, [37] and may be used to confirm a diagnosis already made using clinical signs. [20] Consolidated areas appear white on an X-ray film. [42]
Early investigators distinguished between typical lobar pneumonia and atypical (e.g. Chlamydophila) or viral pneumonia using the location, distribution, and appearance of the opacities they saw on chest x-rays. Certain x-ray findings can be used to help predict the course of illness, although it is not possible to clearly determine the ...
Other x-ray findings that can be seen with foreign body aspiration include obstructive emphysema, atelectasis, and consolidation. [ 8 ] While, x-ray can be used to visualize the location and identity of a foreign body, rigid bronchoscopy under general anesthesia is the gold-standard for diagnosis since the foreign body can be visualized and ...

A chest x-ray of a patient with severe viral pneumonia due to SARS. In adults, viruses account for about one third of pneumonia cases, [12] and in children for about 15% of them. [44] Commonly implicated agents include rhinoviruses, coronaviruses, influenza virus, respiratory syncytial virus (RSV), adenovirus, and parainfluenza.
