Reported cases have predominantly involved the distal extremities and temporomandibular joint, with no previously reported spinal cases. We present the first reported spinal epidural lesion morphologically consistent with CCMN. A 40-year-old male presented with progressive mid-thoracic back pain after a self-reported febrile illness. Imaging demonstrated a T10-T12 posterior\/right calcified epidural lesion causing severe canal stenosis and cord compression. The patient underwent T9-T12 laminectomy and decompression. Intraoperatively, a white, highly adherent epidural mass rather than purulent material was encountered. Histopathology revealed a calcified spindle cell lesion with chondroid differentiation morphologically consistent with CCMN. Follow-up magnetic resonance imaging at 12\u00a0months demonstrated no significant residual canal stenosis, and the patient remained asymptomatic at 18-month clinical follow-up. Recognition of CCMN in this location is important when more common spinal pathologies are suspected.<\/jats:p>","DOI":"10.1093\/jscr\/rjag802","type":"journal-article","created":{"date-parts":[[2026,8,21]],"date-time":"2026-08-21T11:46:33Z","timestamp":1787312793000},"source":"Crossref","is-referenced-by-count":0,"title":["Spinal
