The winking eye or winking owl sign refers to the appearances of the spine, when a pedicle is absent - almost always due to a bony metastasis. The usual appearance of the pedicles representing two eyes on the AP projection is lost, as one pedicle is destroyed - it then appears like one eye is open and the other is winking or shut. Breast cancer and lung cancer are the usual primary tumour culprits. Read more: http://radiopaedia.org/articles/the-winking-owl-sign

Pulmonary TB

Primary pulmonary tuberculosis in boy with typical radiographic findings. Chest radiograph shows patchy consolidation, nodules, and cavities (arrows) in bilateral upper lung zones.

A lung abscess is a circumscribed collection of pus within the lung, is are potentially life threatening. They are often complicated to manage and difficult to treat.  The classical appearance of  a pulmonary abscess is a cavity containing an air-fluid level.   CT is the most sensitive and specific imaging modality to diagnose a lung abscess.

Lobar pneumonia (also known as a non-segmental pneumonia or focal non-segmental pneumonia) is a radiological pattern associated with homogenous, fibrinosupparative consolidation of one or more lobes of a lung in response to a bacterial pneumonia.   Characteristically, there is homogenous opacification in a lobar pattern. The opacification can be sharply defined at the fissures, although more commonly there is segmental consolidation.  http://radiopaedia.org/articles/lobar-pneumonia

Pneumomediastinum

Typical appearances of a pneumomediastinum and pulmonary interstitial emphysema in a young adult. The chest x-ray shows a good example of the continuous diaphragm sign. Asthma is the most likely cause.

A tension pneumothorax occurs when intrapleural air accumulates progressively in such a way as to exert positive pressure on mediastinal and intrathoracic structures. It is a life threatening occurrence requiring rapid recognition and treatment is required if cardiorespiratory arrest is to be avoided. http://radiopaedia.org/articles/tension-pneumothorax

A tension pneumothorax is a critical result and mandates immediate physician-to-physician communication. Document the time and date of your communication in the radiology report.

The deep sulcus sign on a supine chest radiograph is an indication of a pneumothorax.  In a supine film (common in the ICU), it may be the only indication of a pneumothorax because air collects anteriorly and basally, within the nondependent portions of the pleural space, as opposed to the apex when the patient is upright.  The costophrenic angle is abnormally deepened when the pleural air collects laterally, producing the deep sulcus sign.  http://radiopaedia.org/articles/deep-sulcus-sign

Sarcoidosis | Radiology Case | Radiopaedia.org

SARCOIDOSIS There is a widespread, predominantly reticulonodular pattern with relative sparing of the lung bases. There is widening of the right paratracheal stripe and a bulky left hilum in keeping with underlying lymphadenopathy.

A must not miss. Finals film. A tension pneumothorax requires recognition and rapid decompression. Even if all you perform is a needle thoracostomy (e.g. 14G intravenous cannula) inserted in the 2nd intercostal space in the midclavicular line you will save a life as you gain valuable time, before a larger underwater drain can be inserted. http://radiopaedia.org/cases/tension-pneumothorax-17

Pneumothorax due to rib fractures | Radiology Case | Radiopaedia.org

The first taken x-rays in the ED reveals multiple, partial dislocated rib fractures and a pneumothorax on the right side. After insertion of a thoracic drainage, felt necessary due to the multiple fractures, progressive shortness of breath and t.
