Synonyms and keywords: PE
- Chest X-rays are often done on patients with shortness of breath to help rule-out other causes, such as congestive heart failure and rib fracture. Chest X-rays in PE are rarely normal,[1] but usually lack signs that suggest the diagnosis of PE (e.g. Westermark sign, Hampton hump).
- Only 12% of the CXRs in PIOPED were interpreted as normal
- The most common chest x-ray (CXR) finding is atelectasis, seen in 69%.
- Other, more ‘classic’ findings include
- Westermark sign (focal oligemia)
- Hampton hump (a peripheral wedge-shaped density above the diaphragm)
- Palla's sign (an enlarged right descending posteroanterior).
