目的 :探讨颅盖骨转移瘤的 CT表现及诊断价值。方法 :对经临床或病理证实的 2 3例颅盖骨转移瘤病人进行回顾性分析。 2 3例均作有 CT及 X线平片检查。结果 :CT表现主要呈溶骨性骨质破坏 18例 (78.3% ) ,也可见成骨性 2例(8.7% )或混合性 3例 (13% )骨质改变。 X线平片阳性 14例 (6 0 .9% )。转移部位以顶骨 (40 .7% )和枕骨 (2 7.1% )常见 ,颞骨 (11.9% )较少。结论 :CT扫描显示病变明显优于 X线平片 ,具有特征性 ,能对多数病变作出正确诊断
Objective: To investigate the CT findings and diagnostic value of calyx metastases. Methods: A retrospective analysis was performed on 23 patients with calyx metastases who were clinically or pathologically confirmed. All 23 patients underwent CT and X-ray examination. Results: CT showed osteolytic osteolysis in 18 cases (78.3%), and 2 cases (8.7%) were osteogenic or 3 cases (13%) were mixed. X-ray film positive in 14 cases (60.9%). Metastases in the parietal bone (40.7%) and occiput (21.7%) were common with less temporal bone (11.9%). Conclusion: CT scan showed that the lesions were significantly better than the plain radiographs, with the characteristics of the correct diagnosis of most lesions
