Pulmonary Embolism-Spiral CT

Pulmonary embolism (PE) was clinically described in the early 1800s, and von Virchow first described the connection between venous thrombosis and PE. This image shows an intraluminal filling defect that occludes the left pulmonary artery. Also present is an infarction of the corresponding lung, which is indicated by a triangular consolidation and pleural effusion.
