Chordomas are rare malignant tumors arising from notochord remnants, typically affecting the sacrococcygeal region. We report the case of a 60-year-old woman with a history of goiter treated with Levothyrox who presented with chronic right-sided sciatica evolving over more than one year. CT imaging revealed a large heterogeneous mass measuring 82×71×70 mm in projection of the right S1, S2, and S3 foramina, heterogeneously enhancing after contrast injection. The lesion completely filled the sacral canal, caused extensive osteolysis of the adjacent vertebral bodies, and occupied the right sacral foramina. This case highlights the importance of CT in diagnosing sacral chordomas and assessing the extent of bone destruction.
