脊髓髓内转移性肿瘤(ISCM)临床非常少见,约占脊髓髓内肿瘤的0.1％-0.4％[1]。多数是在肿瘤患者尸检中发现(O.9％-21％)[2]。随着影像学技术的发展,特别是MRI的应用,ISCM的发现率不断上升。尽管MRl非常敏感,但并无特异性,而临床症状对确诊亦无甚帮助[1,3],因而,ISCM多是被外科手术或尸检所证实。此病在治疗方法上仍有争议,治疗结果也难令人满意,但积极治疗可提高生存质量,延长生存时间。现将我们遇到的3例ISCM报道如下,以期提高对该病的认识。 Spinal intramedullary metastatic tumors (ISCM) clinically very rare, about spinal cord intramedullary tumors of 0.1% -0.4% [1]. Most of the autopsy tumor patients found (O.9% -21%) [2]. With the development of imaging technology, especially the application of MRI, the detection rate of ISCM is on the rise. Although MRL is very sensitive, it is not specific, and clinical symptoms are not helpful in diagnosing [1,3]. Therefore, most ISCMs are confirmed by surgery or autopsy. The disease is still controversial in treatment, the treatment results are difficult to satisfactory, but aggressive treatment can improve the quality of life and prolong survival time. We now encounter three cases of ISCM reported below, with a view to raising awareness of the disease.
