The most common malignant primary spinal neoplasm in adults is plasmocytoma (30 %) and other malignant tumors in adults include chondrosarcoma and osteosarcoma. Chordoma represents about 2–4 % of all spinal column tumors, 40 % of primary spinal tumors and has a high propensity for the sacral and cervical regions. Incidence of primary malignant vertrebral tumors is correlated with patient’s age. The risk increased significantly when patients were older than 40 years. CT and MRI are both required for proper diagnosis, with correlation of findings to age and clinical presentation. Biopsy can identify tumors and accurately determine the type, grade, and stage of tumors. Complication rates for percutaneous biopsy range between 1 and 3 %, compared to 16 % for open biopsy. Lower accuracy rates have also been reported in fibrotic, collagenous, and inflammatory lesions, as well as for specific lesions such as aneurysmal bone cysts and hemangiomas. Osteolytic or mixed lesions have a reported diagnostic yield of up to 88 %, compared with sclerotic lesions at 67 %.</div></div><div><h3>Conclusions</h3><div>Final nine consensus statements provide current, evidence-based guidelines on the incidence, epidemiology, classification and radiographic diagnosis of primary vertebral tumors for practicing spine surgeons worldwide.</div></div>","PeriodicalId":38138,"journal":{"name":"Interdisciplinary Neurosurgery: Advanced Techniques and Case Management","volume":"42 ","pages":"Article 102127"},"PeriodicalIF":0.5,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145325124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
