| Abstract: | Objective:To analyse the characteristics of osteoid osteoma on CT imaging.Methods:CT imaging of 38 cases of osteoid osteoma proved by surgery and pathology were retrospectively analysed.Results:Among the 38 cases,the affected sites were the femur (n=21),tibia (n=5),humerus (n=3) and other bones (n=9).37 cases had central calcified nidus,33 cases had sclerotic margin,13 had periosteal or endosteal bone formation.There was bony absorption in the medullary cavity in 9 cases.Conclusion:CT imaging of osteoid osteoma is quite typical and CT is a good modality for diagnosis of the disease. |
