(a) Staging chest CT scan obtained 24 hours after lymphography shows several peripheral areas of pulmonary consolidation (arrowheads), which are due to pulmonary infarction. (b) Anteroposterior chest radiograph shows subtle, asymmetric, peripheral areas of increased opacity in the lungs (greater on the left than on the right).
