Fig. 6. A 68-year-old male with right pleuritic chest pain and ipsilateral flank area pain.

A, B. CT pulmonary angiogram (A) cropped coronal image shows a filling defect (arrow) in the right posterior basal subsegmental branch consistent with pulmonary embolism. (B) Sagittal CT chest lung window shows a focal ground-glass (circle) consistent with an evolving infarct in the posterior basal right lower lobe corresponding to an area of decreased perfusion (notched arrow) evident on (C) iodine overlay maps.
