摘　　要：目的　分析骨巨细胞瘤的X线及CT征象 ,并作比较。方法　分析 5 3例经手术病理证实的骨巨细胞瘤的X线平片及CT表现 ,并予以评分。结果　骨巨细胞瘤以囊性膨胀性偏侧性骨破坏为主者 3 9例 ,其余为单纯溶骨性骨破坏。多数病例出现骨壳 ,骨壳完整者X线片 18例 ,CT 13例 ,不完整者X线片 2 1例 ,CT 2 6例。CT观察病灶内多无分隔。骨质破坏边缘多清晰 ,CT观察 19例有不同程度的硬化边。病灶内软组织密度多不均 ,11例CT可观察到液液平面。骨壳不完整者常见骨外软组织块影。结论　通过X线片及CT对骨巨细胞瘤表现的比较研究 ,CT在诊断骨巨细胞瘤上明显优于X线平片 ,对长骨巨细胞瘤进行评分有助于术前分级。Objective To analyze X-ray plain film and CT signs of giant cell tumor of bone.Methods Imaging findings of giant cell tumor in 53 cases proved surgically and pathologically were retrospectively analyzed.Results 39 cases appeared as expensive cystic and eccentric destruction,osteolytic destruction 14 cases.Bone crests were usually seen in (39/53).Most of lesions did not have bone septations on CT image.The borders of destructive bone were clear and existed complete or incomplete sclerotic borders in 19 on CT image.The inner soft tissues of lesions were heterogeneous in most of the cases.Fluid-fluid level could be seen in 11 cases.The soft tissue masses outside the bone were demonstrated in the majority cases with discontinuous bone shell.Conclusion CT is more helpful than X-ray plain films in diagnosis of giant cell tumor of bone.
