The CT Manifestations of Giant Cell Tumor of Bone / 实用放射学杂志

ABSTRACT

Objective To analyse CT signs of giant cell tumor of bone.Methods CT appearances of 42 cases of giant cell tumor of bone were reviewed.All patients were pathological proven.Results (1)Two kinds of bone destruction were seen in all asesexpansive cystic destruction and osteolytic destruction.The anterior was predominantly.(2)Most of our patients haven't bone septations in their tumors (95.2%).(3)Bone crests were usually seen in our study(63.2%).(4)Complete or incomplete sclerotic borders existed in 44.7% of all cases.(5)The inner bone soft tissues were heterogeneously in most of the patients.Fluid-fluid level can be seen in 5 cases (11.9%).(6)The outer-bone soft tissue masses were demonstrated in the majority cases with discontinuous bone shell.Conclusion CT may deepen our understanding and add imaging signs about giant cell tumor of bone;Which can enhance our diagnostic and differential diagnostic capability.
