Overview
Aspiration pneumonia chest x ray
Plain films
- AP portable chest images may demonstrate bilateral opacities in the middle or lower lung zones.
- On PA and lateral images, the opacities may be localized to the posterior segments of upper lobes or to the superior segments of lower lobes.
- Lung abscess
- Empyema
- Involvement of dependent pulmonary lobes i.e., upright position lower lobe, superior segment of lower lobes or posterior segment of upper lobes in recumbent position
CT
- Aspirated low-density organic material such as mineral oil in the tracheobronchial tree or alveolar spaces cannot be diagnosed on plain radiographs, but they can be demonstrated and perhaps measured on CT scans.
- Opaque aspirates are also well demonstrated on CT scans.
