目的：探讨Ｘ线平片在成软骨细胞瘤诊断中的临床价值。方法：分析１９例成软骨细胞瘤的临床和Ｘ线表现。结果：Ｘ线表现囊状破坏伴骨皮质膨胀１２例，单纯囊状破坏７例，无不规则或溶骨性破坏。病变呈云絮状密度增高８例，砂粒状和斑点状骨化或条片状钙化４例。结论：Ｘ线平片对成软骨细胞瘤的诊断具有重要意义 Objective: To investigate the clinical value of X-ray film in the diagnosis of chondroblastoma. Methods: The clinical and radiographic findings of 19 patients with chondroblastoma were analyzed. Results: X-ray showed cystic destruction with cortical expansion in 12 cases, simple cyst damage in 7 cases, no irregular or osteolytic destruction. Pathological changes were cloud-like density increased in 8 cases, gritty and speckled ossification or patchy calcification in 4 cases. Conclusion: X-ray is important for the diagnosis of chondroblastoma
