The CT scan done on admission showed an infiltrating pelvic mass (12 x 8 x 6 cm) extending through the sciatic foramen to the left gluteus and thigh (fig. 1).
Postembolization contrast CT study showing total devascularization and regression of the pelvic lesion.

At the control, complete regression of the pelvic mass and its vascularization were seen on the CT scan (fig. 2).
Imaging findings. a Angiographic aspect: tumor occupying the left thigh before embolization. b Limb angiography: main feeder of remaining tumor of the gluteus. c Fluoroscopy: selective catheterization of the profunda femoris artery. Onyx-18 injection.

Surgical dissection of the left femoral artery and then partial embolization of the remaining tumor using a gelatin sponge (Spongostan Haemostatic) were successfully performed (fig. 3a). The contralateral, left lower-limb angiography done with a 4-french, shaped Cobra catheter (Glidecath, Terumo, Tokyo, Japan) showed the main supply of the hypervascular tumor in the gluteus (fig. 3b). Angiographic devascularization was achieved under fluoroscopy after injection of 0.8 ml of a nonadhesive, liquid glue, Onyx-18 (ethylene vinyl alcohol copolymer, Micro Therapeutics, Irvine, Calif., USA) (fig. 3c).
