[edit] Discussion of Chondroblastoma

  • Chondroblastomas are benign cartilaginous lesions
  • Represent less than 1% of all bone tumors
  • Most common presenting symptom is pain, which may be severe and limit movement in the adjacent joint.
  • Most patients are less than 20 years of age
  • Men are more commonly affected than women.
  • Chondroblastoma does not undergo spontaneous resolution if left untreated; therefore, intervention is necessary to stop progression and alleviate pain.
  • Treatment options include:
    • Curettage and packing of the area with bone graft or polymethylmethacrylate.
    • Focused radio-frequency heat ablation.

[edit] Imaging Findings for Chondroblastoma

  • Chondroblastomas are well defined lytic lesions arising in the epiphysis or apophysis of a long tubular bone such as the femur, humerus, and tibia.
  • Calcifications are seen in up to 50% of cases.
