title: CT patterns of mural thrombus in aortic aneurysms.
abstract: The computed tomography (CT) scans of 71 cases of arteriosclerotic and/or dissecting aortic aneurysms (33 thoracic, 25 abdominal, and 13 thoracoabdominal) were analyzed. Enlargement was seen in all cases, and deformity of aorta was found in 92%. Mural thrombus was evident on CT in 86% of the cases, and its pattern was classified into eight types. The most frequent was the ring type (Type A) followed by the left crescent thrombus (Type H) and the left posterior crescent thrombus (Type D). Calcification was found in 60 cases, and intraluminal calcification was seen in 14 cases.
