CTICasesPulmonary Embolism with Regional Lung Edema
Imaging findings
Unilateral left upper lobe consolidation in an intubated patient with extensive PE in other pulmonary territories.
Key takeaways
Pulmonary embolism can alter blood flow distribution so significantly that the non-obstructed regions receive an excess of cardiac output, potentially leading to regional acute lung injury (stress failure of capillaries) rather than typical hydrostatic edema.
