Pulmonary tumor embolism is a rare cause of respiratory failure in patients with cancer and is only infrequently diagnosed during life. Chest radiographs are usually normal. Dilated and beaded peripheral pulmonary arteries may be present on computed tomography scans. The authors describe an unusual case of pulmonary tumor embolism presenting on computed tomography scans as bilateral, peripheral, wedge-shaped opacities. On autopsy, these opacities corresponded to areas of pulmonary infarction.
