AAA with a maximum diameter of 17 cm but no clear delimitation because of its extension along the paravertebral spaces where it formed a mass with features consistent with a blood clot (the same mass that previously was considered a retroperitoneal tumor) (Figure 1). An erosion of the anterior surface of the L3 and L4 vertebral bodies was also noted (Figure 2).
