Giant Cell Tumor

• Giant cell tumor is a relatively common and
  locally aggressive bone tumor
• Usually giant cell tumors are found in the long
  bones, especially in the distal femur and
  proximal tibia (50-65 of giant cell tumors occur
  around the knee)
• When giant cell tumors occur in the pelvis, they
  usually are located near the sacroiliac or hip
  joints (arrow)
• Giant cell tumors are osteolytic lesions,
  extending to subchondral bone in the long bones,
  usually without a significant sclerotic rim
