Abstract：Objective: To study the clinical and X-ray, CT appearance and pathological speciality of chondroblastoma. Materials and Methods: X-ray examination was performed in 16 cases, CT scanning was performed in 8 cases. Twelve cases were males and 4 cases were females. The youngest one was 6 years old and the oldest one was 47 years old. Results: Four cases were in tibia, 5 cases in femur, 3 cases in humerus, each of the acetabulum, calcaneus, talus and scapula had 1 case. Cystic and expansive damage of bone(9 cases), cyst-like destruction(5 cases), invaded destruction(1 case). Eccentric-type(12 cases), Y-aixs type(4 cases), glass-like density(2 cases), short bone protuberance(6 cases); sand-like or spotty sclerosis(11 cases), partial disappearce of bony cortex(6 cases), osteosclerosis(12 cases), periosteal reaction(1 case); articalas involvement(2 cases), mass of soft tissue(5 cases). Diameter of bone lesion was 5~9cm. Conclusion: Chondroblastoma had its specificity, but imaging finding, and pathology had many varieties. It’s should be differentiated from other relative lesions. The final diagnosis depends on pathology.
