摘　　要：本文报告５３例（１２３个脊椎）经ＣＴ扫描确定的脊椎转移，其中２６例作Ｘ线平片检查，所有病例均经临床病理证实。原发性以肺癌、乳腺癌、肝癌和前列腺癌较多见，ＣＴ表现呈溶骨性３８例（７１．７％），混合性９例（１６．９％），和成骨性６例（１１．３％）。椎体是脊椎转移瘤最常累及的部位，这与血管进入脊椎的部位有关。转移最初的部位是椎体的后部，椎弓根破坏为椎体后部破坏扩展所致。ＣＴ扫描在发现病变和估价病变方面较Ｘ线平片敏感。Fifty three patients (123 vertebrae) of spinal metastases confirmed by clinico-pathology, and in whom both CT scan (53 patients) and plain films (26 patients) of the spine were presented. The primary tumors were mostly cacinomas of the lung. the breast, the liver and the prostate. CT findngs mainly presented lytic type in 38 cases (71.7%), mixted type in 9 cases (16.9%), and osteoblastic type in 6 cases (11.3%). The body of the vertebra is most altered. It is supposed that the location of vertebral bone destruction followed the entry site of the vertebral vessels. The initial location of metastases is in the posterior portion of the body. Destruction of the pedicle occurs in combination with invasion of the vertebral body.CT scan on detection and evaluation for metastatic lesion is more sensitive than plain film.
