A case of malignant lymphoma invading the aorta, which mimicked aortic dissection

Abstract

In rare cases, malignant lymphoma may invade the aorta and mimic other aortic diseases; thus, it is sometimes difficult to diagnose from image examinations. In such patients, aortic disease may also be caused by degeneration of the aortic wall or necrosis due to chemotherapy. We present the case of a 78-year-old man who was initially diagnosed with an aneurysm or tumor adjacent to the aorta, in which open surgery was required for replacement of the abdominal main vessel. We discuss treatments for malignant lymphoma invading the aorta with reference to previous reports.
