Figure 1: Preoperative CT exam of the pelvis revealed an aggressive mass
involving the right ilium (arrow) and lateral sacrum (arrowhead).
Figure 2: Histopathologic image (hematoxylin and eosin stain) of the
tumor exhibiting moderate pleomorphism and moderate mitotic activity
with no undifferentiated areas - consistent with a grade II
chondrosarcoma (10x magnification; bar = 100µm)
Figure 3: Lateral and ventrodorsal pelvic radiographs twenty-seven days
following iliectomy pelvic radiographs demonstrated an overlapping
fracture of the left pubic bone as well as corresponding fracture of the
left ischial arch with evidence of callus formation over the fracture
sites.
Figure 4: CT image of the pelvis fifty-three days after iliectomy for
marginal excision of ilial chondrosarcoma. A portion of the prolene mesh
can be seen as a linear serpiginous region of hyperattenuation (arrow).
Figure 5: Pelvic radiographs 488 days post-iliectomy revealing new bone
formation within the right hemipelvis region where the hemipelvectomy
was performed cranial to the coxofemoral joint. The prolene mesh implant
can be visualized. The right proximal femur is slightly more osteopenic
compared to the left.
