Associated lymphoma and abdominal aortic aneurysm demonstrated by computed tomography.

In a review of 260 cases of lymphoma, there were 6 patients with an aneurysm of the abdominal aorta. In four cases there was surrounding abdominal lymphadenopathy. The diagnosis was established by computed tomography (CT) because of calcification in the aortic wall was visible on the scans in all 6 cases. This calcification was not sufficiently clear to permit identification of the aneurysm on plain films in three of the cases. In two cases without abdominal lymph-adenopathy, contrast-filled nodes delineated the outer margin of the wall of the aorta.
