摘要
目的分析脊柱单发椎体肿瘤及肿瘤样病变的影像学表现,以提高认识。材料和方法收集经手术病理证实的34例脊柱单发椎体肿瘤及肿瘤样病变,分析内容包括骨质破坏形式、边缘有无硬化、病变内部密度或信号特征、有无软组织肿块形成以及强化方式等。结果 (1)良、恶性病变在骨质破坏、软组织肿块形成、边界及椎管受侵与否等方面存在差异,而在硬化边、病灶内瘤骨或钙化、残存骨以及强化方式上差异不明显。(2)影像学上无骨质破坏型均见于良性病变,单纯骨质破坏型良、恶性均可发生,骨质破坏伴软组织肿块型以恶性病变为主。结论脊柱单发椎体肿瘤及肿瘤样病变具有一定规律,掌握其特点有助于良恶性病变的诊断及鉴别诊断。
Objective To analyze the imaging features of solitary tumor and tumor-like lesions in spine and improve the understanding of those diseases. Matiecials and Methods 34 cases of solitaW tumor and tumor-like lesions confimed by pathological were analyzed, including osteolytic destruction, marginal sclerosis in the edge or not, intralesional density or signal features, soft tissue mass or not and the enhanced mode. Recsults （1）There were differences between benign and malignant lesions in the osteolytic destruction, soft tissue mass, boundary and spinal involvement; and there existed no obviously difference in marginal sclerosis, intratumoral bone or calcification and enhanced mode.（2）No osteolytic destruction was found in benign lesions, while purely osteolytic destruction pattern could be benign or malignant lesions, and osteolytic destruction associated with soft tissue mass mainly fonnd in malignant lesions. Conclusion Solitary tumor and tumor-like lesions in spine have certain rules, which contribute to differential diagnosis.
