Images illustrate the case of a 63-year-old woman, diagnosed with a two-level (L3–L4) synovial sarcoma with involvement of bifurcation of the aorta. (A–D) MR images show a tumor spanning across L3–L4, involving the aorta. (E) Through an anterior approach, the bifurcation of the aorta was exposed. (F) The aorta was ligated above and below the involved area and a bypass graft was created with the aid of a vascular surgeon. The bifurcation was left in situ with the tumor and was resected en bloc through a posterior approach. (G) The tumor was removed en bloc along with the L3 and L4 bodies and bifurcation of the aorta.
