A solid mass measuring approximately 13.2 x 8.9 x 11.5 cm can be seen, which displaces vascular structures to the contralateral side, extends to the floor of the pelvis, and infiltrates the muscles: the right iliopsoas, obturator internus, medial aspect of the right gluteus medius, and right piriformis muscle. A bone window in an axial cut shows a lytic lesion at the level of the right iliac bone.
