Malignant fibrous histiocytoma arising from the aortic wall mimicking a pseudoaneurysm with ulceration.
Malignant fibrous histiocytoma of the thoracic aorta associated with ulcer-like projection has not been reported previously. The hypovascular tumor of the thoracic aorta involved the mural layer, which showed intra- and extra-mural growth patterns and no significant filling defect within the aortic lumen, and mimicked ulcer-like projection with secondary pseudoaneurysm formation. Aortic tumor, although rare, should be included among the causes of an ulcer-like projection.
