Metastatic disease involving the discovertebral junction of the spine

Our results lend further support to the theory that metastatic tumors can invade the cartilaginous endplate through defects in its substance, allowing direct contact of tumor and disc. Minimal tumor invasion of the discovertebral junction may not be identified at magnetic resonance imaging or gross anatomic inspection, or both, because small metastatic foci may be obscured by abnormalities in the morphology of the cartilaginous endplate.
