contrast-enhanced CT image shows fusiform aneurysm and wall thickening of
descending thoracic aorta (arrows). This finding suggests active
inflammatory process.

Fig. 5B. —56-year-old woman with Takayasu's arteritis. Unenhanced CT
image obtained 5 years after A shows size of aorta has not changed.
Calcification of aortic wall has become much heavier. Calcification indicates
chronic arteritis.
