Aortitis is a serious complication of giant cell arteritis (GCA), because of the risk of aortic aneurism, rupture, or dissection. Aortitis is present either at presentation or, more frequently, occurs as a delayed complication, typically as an aortic aneurism of the ascending part of the aorta. An aortic aneurism may occur in up to 10% of patients. ⋯ When present at the time of diagnosis of GCA, these findings seem to be associated with frequent relapses and perhaps with a higher long-term vascular mortality rate. Therefore, we recommend the screening of aortitis lesions at GCA diagnosis by an aortic CT-scan and follow-up. Therapeutic trials should be conducted to try to improve the treatment of aortitis in GCA.
