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.
 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.
