Endoleak is the classical cause of rupture of aneurysms previously treated by endovascular means. We report a rare case of a retroperitoneal liposarcoma (LIS) invading an abdominal aortic aneurysm (AAA), previously treated by endovascular repair (EVAR), causing rupture. Furthermore, a brief discussion of the diagnostic challenges posed by retroperitoneal tumors is presented with a closing note on their management.
