Abstract：Objective: To analyse the imaging appearances and to evaluate the diagnostic value of X-ray, CT and MRI in giant cell tumor of bone. Methods: Seventy-six cases of various giant cell tumor proved by pathology, their imagings features were analyzed. Result: Twenty-nine cases of cystic type had eccentric expanding destruction of bone at the end of long bone extremities. 39 cases of osteolytic type had discontinuous cortex of bone and blurred tumor margins. Eight malignant cases had moth eaten destruction of the bone with periosteal reaction and fast-growing soft tissue mass. Liquid-liquid level in MRI imaging were found in 19 cases with aneurysmal bony cyst. In 9 cases there were recurrence, the bony implant area was replaced by tumor tissues. Conclusion: Most of the GCT have typical radiological appearances and there is no difficult in making a correct diagnosis, CT and MRI supply more information and the capability of differential diagnosis may be improved.
