Case of the Week: Pulmonary Infarction (X-ray & CT)

Listen Later

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:

  • Uncommon complication of pulmonary embolism.
  • Most common in right lung.
  • Risk of infarction increases with large clot burden.
  • Typically wedge-shaped, peripheral consolidation with no air bronchograms (Hampton hump).
  • However, may not be wedge-shaped, and not all wedge-shaped opacities will be infarcts in the setting of pulmonary embolism.
  • “Bubbly” consolidation containing rounded, central lucencies: Most specific finding of infarct* and represents a combination of infarcted, necrotic lung and adjacent viable, aerated lung.
  • “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.
