Patients commonly present with insidious back pain, sometimes with a focal mass, and constitutional symptoms are uncommon early in the disease course. As clinical features are often nonspecific and may overlap with degenerative, infectious, and metastatic disease, imaging plays an important role in lesion identification, characterization, and treatment planning. Computed tomography helps to define osseous architecture and matrix characteristics. Magnetic resonance imaging can assess marrow involvement, soft tissue extension, neural compression and intra-canal disease, and tumor vascularity. Together, advanced imaging modalities guide further workup, optimize biopsy planning, inform prognostic assessment and therapeutic decision-making, and anticipate mechanical instability or neural compromise. This narrative pictorial review synthesizes radiographic, CT, and MRI appearances of primary spinal tumors across major histologic lineages (e.g., osteogenic, chondrogenic, notochordal, vascular), illustrated with representative cases. We correlate imaging with clinical presentation to distinguish typical from atypical variants and highlight mimics and pitfalls with implications for diagnostic interpretation and management.<\/jats:p>","DOI":"10.3390\/diagnostics15232970","type":"journal-article","created":{"date-parts":[[2025,11,24]],"date-time":"2025-11-24T10:24:17Z","timestamp":1763979857000},"page":"2970","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Unveiling Primary Bone Tumors of the Spine: A Review of Essential Imaging Clues"],"prefix":"10.3390","volume":"15","author":[{"given":"Noah","family":"Tregobov","sequence":"first","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, University of British Columbia, Vancouver, BC V5Z 1M9, Canada"},{"name":"Vancouver-Fraser Medical Program, Faculty of Medicine, University of British Columbia, Vancouver, BC V5Z 1M9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michal","family":"Krolikowski","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, University of British Columbia, Vancouver, BC V5Z 1M9, Canada"},{"name":"Division of Neuroradiology, Department of Radiology, Vancouver General Hospital, University of British Columbia, Vancouver, BC V5Z 1M9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Dragoman","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, University of British Columbia, Vancouver, BC V5Z 1M9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin","family":"Brakel","sequence":"additional","affiliation":[{"name":"Vancouver-Fraser Medical Program, Faculty of Medicine, University of British Columbia, Vancouver, BC V5Z 1M9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter L.","family":"Munk","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, University of British Columbia, Vancouver, BC V5Z 1M9, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0040-6054","authenticated-orcid":false,"given":"Manraj K.
