脊柱转移瘤的CT诊断：附41例分析

笔者报告４１例脊柱转移瘤的ＣＴ表现。原发灶以肺癌、乳腺癌和肝癌较多见。ＣＴ表现主要呈溶骨性（６８．３％），亦可呈成骨性（１４．６％）或混合性（１７．１％）。本组４１例中２０例作平片Ｘ线检查。ＣＴ扫描在发现和估价病变方面较平片Ｘ线检查为敏感，如ｘ线平片发现骨破坏仅为５５％，ＣＴ扫描为１００％；Ｘ线平片显示椎管受累为１４％，ＣＴ扫描为６５％。对脊柱转移瘤的ＣＴ表现、ＣＴ诊断和鉴别诊断价值等进行了讨论。

CT Diagnosis of Spinal Metastasis (Report of 41 Cases)

The authors reported the CT findings of spinal metastasis in 41 cases 20 of which alsohad plain radiographs.The most common sites of primary carcinoma were the lung, breast,and liver. On CT,the metastases presented as lytic type(68.3%),osteoblastic type(14.6%),and mixed type(17.1%).CT is far more sensitive in detecting and evaluating these lesions than routine radiography. For example, detectability was only 55% with plain radiograph and 100% with CT. Spinal canal com-promised by lesion was detected in 14% with plain radiography,and in 65 % with CT scanning. Evaluation of CT in diagnosis and differential diagnosis of spinal metastasis was discussed.
