目的：探讨脊椎结核与脊椎转移瘤的ＣＴ形态差异。方法：：回顾性分析和比较２７例脊椎结核和２４例脊椎转移瘤的ＣＴ形态表现，拟定出ＣＴ形态差异指标进行鉴别诊断。结果：脊椎结核多发生于椎体前中部、多以多发和弥散形式出现、病灶内可有死骨；脊椎转移瘤多以单发形式出现、多发生于椎体中后部和附件骨、病灶内少有死骨；结核椎旁肿块常有钙化、多无强化或仅周边强化，而转移瘤椎旁肿块少有钙化、强化明显；结核常累及椎间盘，而转移瘤罕有累及椎间盘。结论：上述ＣＴ形态差异指标的应用，有助于两类病变的鉴别诊断
Objective: To investigate the differences of CT morphology between spinal tuberculosis and spinal metastases. Methods: The CT features of 27 cases of spinal tuberculosis and 24 cases of spinal metastases were retrospectively analyzed and compared, and the differential diagnosis of CT morphological indexes were drawn. Results: Spinal tuberculosis occurred in the anterior vertebral body, mostly in multiple forms and diffuse forms, there may be dead sebaceous lesions; Spinal metastases mostly in the form of single, mostly in the posterior vertebral and appendage bone, lesions There are few sequestrum; tuberculosis paravertebral mass often calcification, no enhancement or only peripheral enhancement, and metastatic tumor paravertebral mass rare calcification, enhanced significantly; tuberculosis often involving the intervertebral disc, and metastases rare involving the disc. Conclusion: The application of the above-mentioned CT morphological differences index can contribute to the differential diagnosis of two types of lesions
