Which of the following radiological sign will be present in a young lady with symptoms suggestive of pulmonary embolism?
Correct Answer: All of the above
Description: Pulmonary infarction may occur if the pulmonary venous pressure is elevated or the bronchial aerial supply to a region is deficient. The cone-shaped area of pulmonary infarction has been called a Hampton's hump. An area of radiolucency, corresponding to diminished pulmonary vascularity distal to a pulmonary embolism, is occasionally seen and is called the Westermark sign. There may also be an increase in the size of the pulmonary aery proximal to a large central pulmonary embolus (Fleischner sign). Ref: Chiles C., Gulla S.M. (2011). Chapter 4. Radiology of the Chest.
