We presented here 2 cases of rare nonvascular tumor involving the aorta. Case 1: A 69-year-old woman. She presented leg edema and dyspnea on admission. Computed tomography revealed abdominal aortic aneurysm perforating left common iliac vein. Abdominal aortic aneurysm replacement and fistula closure were done on an emergency basis. Immunohistologic examination revealed that malignant mesothelioma invaded the aortic wall. Case 2: A 47-year-old woman presented with dyspnea. Enhanced computed tomography revealed rupture of the descending aortic aneurysm (saccular type). Aortic replacement was done on an emergency basis. One year after the operation, computed tomography revealed a giant mass (160×70mm) surrounding the descending thoracic aorta. On biopsy, malignant schwannoma was found to invade the descending aorta. Sometimes nonvascular tumors form aneurysms. So we should be careful in diagnosis before operation.
