Abstract:
Objective To analyze X-ray,CT and MRI characteristics of chondroblastoma.Methods Imaging(CT,X-ray and MRI)signs of chondroblastoma confirmed by pathology in 22 cases were analyzed.2 cases and 7 cases underwent contrast-enhanced CT and MRI examination respectivety.Results The lesions were located in tibia(n=11),femur(n=4),patella(n=2),humerus(n=1),temporal(n=1),mandibal(n=1),iliac bone with sacrum(n=1).X-ray manifestations were bone destruction(21),stripe or spotty calcification(5)and patchy sclerosis around the lesion(10).On CT,the lesions were lobular-and-oval(14),density of soft tissue(7)with stripe or spotty calcification(15),patchy sclerosis around(15)and soft tissue swelling(18).Mixed signal intensity on T2WI and FS T2WI,patchy long T1 and long T2 signal intensity around the lesions(20).Conclusion The imaging features of benign chondroblastoma are of certain characteristic and most signs on X-ray,CT and MR are corresponded with each other.
