摘要
目的 研究分析脊髓海绵状血管瘤(CA)的临床和放射学特点及治疗效果。方法 回顾分析19年间收治的19例脊髓CA的临床资料。结果 平均病程4.2年,临床主要表现为脊髓压迫症。MR T_1W可见低、高和混杂信号,T_2W高信号多见,个别瘤周可见低信号环。19例脊髓CA全切15例,次全切或部分全切3例,仅作活检1例。17例平均随访5.7年,临床改善及稳定者15例。结论 MR是诊断脊髓CA的敏感方法。手术治疗效果较好,影响病人预后的最重要因素是术前功能状况及瘫痪持续时间。
Objective To study the clinical and radiological features of spinal cavernous angiomas (SCA) and the curative effects of surgery on them. Method Retrospective analysis of the data of 19 cases with SCA treated in the last 19 years was made. Results The mean clinical course was 4.2 years in 19 patients with SCA. Spinal cord compression syndrome was the main clinical manifection. MR T1W showed low or high or mixed signal and most T2W showed high signal. The peri-tumoral ' ring' sign of low T2 signal could be found in the individual case. The tumors were totally removed in 79% (15/19) of the cases. Seventeen cases were followed up for an average of 5.7 years and 88% (15/17) of them experinced clinical improvements or stability. Conclusions SCA is a benign lesion which grows slowly. In some cases, their clinical courses can quite rapidly change because of the occurrence of tumor hemorrhage. MR examination is sensitive to the diagnosis of SCA. The operative results are good and the most important factors influencing the patient's prognosis are the preoperative functional status and the duration of paralysis in the patients with SCA.
