摘要
本文对57例椎骨转移瘤CT表现进行了分析,男多于女,约3:1,平均年龄54.6岁。转移部位以胸、腰椎最多,依次是骶椎与颈椎。原发病灶以肺癌(24.6%),肝癌(14%)转移发生率高。椎体转移灶的CT表现可分为3型。(A)虫蚀状破坏,(B)圆形或不整形的溶解区,(C)斑点状碎裂。(A)与(B)常并存,以肺癌、肝癌、肾癌、鼻咽癌转移至椎骨具多,(C)型多见于原发肿瘤晚期,手术后转移,恶性程度高的病例。作者对受侵附件,软组织改变及脊髓造影所见进行了描述,另外发现椎间盘不受侵,可见椎间盘软骨对肿瘤具有抗力,并根据CT分型能判别原发肿瘤的恶性程度与大致部位。其CT基本征象是溶骨破坏和瘤组织肿块。
The CT expression of 57 cases about spine metastatic tumor were analysed. The ratio ofmale to fema1e was about 3 To 1, and everage age was 54. 6 years old. The number of transfering positionwere lum ber sacral, cervical vertebraes descendingly, and among these metastatic tumors, 1ung and liver asthe prime position were higher (24. 6% and 14 % respectively). The CT expression of metastatic focus couldbe classified to 3 types: (A ) destroing of erose. (B ) dissolve region of round or irregular, and (C ) spot break.(A ) and (B ) were of ten existed together and most of them were cancers of lung, liver, kidneys and nasopharynx, and (C) was frequency more in the cases of later period of prime cancer, transfer after operation andhigh malignant. A uthors also described the display on CT about the change of invaded appendix, soft tissueand CTM. They may be supposed that intervertebral disc soft tissue could resist carcinoma because no anyinvolved interverterbral disc were found. Depending on the classifing of CT expression, the malignant degreeand position of prime cancer can be identified generally, and the basic CT expression of metastatic tumorwete destroy of dissolving bone and lump of tumor tissue.
