- čas přidán 7. 06. 2024
- In this radiology lecture, we discuss the chest x-ray and CT appearance of pulmonary infarction in the setting of acute pulmonary embolism.
Key points include:
1) Uncommon complication of pulmonary embolism.
2) Most common in right lung.
3) Risk of infarction increases with large clot burden.
4) Typically wedge-shaped, peripheral consolidation with no air bronchograms (Hampton hump).
5) However, may not be wedge-shaped, and not all wedge-shaped opacities will be infarcts in the setting of pulmonary embolism.
6) “Bubbly” consolidation containing rounded, central lucencies: Most specific finding of infarct* and represents a combination of infarcted, necrotic lung and adjacent viable, aerated lung.
7) “Vessel” sign: Enlarged vessel leading to apex of a wedge-shaped opacity. Vessel is dilated due to the presence of intraluminal thrombus or distal obstruction.

Thank you
You're welcome!
I sometimes forget to include pulm infarct in my ddx for small consolidations, especially on non-con chest CTs. If really small, and in dependent lobes, I may mistake it for atelectasis. Thanks for the overview!
You're welcome SkeletoPedia, and glad to help!
Thank you, Dr. Kowal!
Most welcome Minette Estrada, and thank you for watching!
thank you very much for enlighting us regarding pulmonary infarction which mimics consolidation and may be overlooked👍👌🙏
You’re welcome!
Excellent work once again. Thank you so much!
Thank you Nikolay, appreciate that!
I had 2 in my right lung
