肝癌骨转移的CT影像表现

CT Features of Skeletal Metastases from Hepatic Cancer

目的 研究肝癌骨转移的 CT表现 ,提高诊断正确率 ,并评价 CT的诊断价值。材料与方法 回顾性分析 116例肝癌骨转移的 CT影像资料 ,其中有普通 X线脊柱摄影 6 5例 ,MR脊柱扫描 36例。结果 116例中 ,2处或 2处以上的骨转移灶 75例(6 4.6 6 % ) ,骨转移好发部位依次为脊椎、骨盆、肋骨、胸骨、头颅等。主要 CT表现为溶骨性骨质破坏伴软组织肿块。结论 CT能清楚显示转移灶骨破坏范围及对周围组织结构的侵犯情况 ,是诊断骨转移的有效方法 。

Objective To study CT features of skeletal metastases from hepatic cancer and to improve the diagnostic accuracy.Materials and Methods CT findings in 116 patients, together with the additional plain film of the spine (n=65) and MRI of the spine (n=36), were retrospectively analyzed.Results Of the total 116 cases, two or more bone metastases were found in 75 (64.66%). The site of predilection was, from high to low, in the following order: spine, pelvis, rib, sternum and skull. The main CT sign was osteolytic destruction with soft tissue mass.Conclusion CT scan can demonstrate the extent of bone destruction and the invasion of the surrounding structures. It is an effective method to diagnose bone metastases, and is helpful in guiding clinical management.
