C1–2 instability from os odontoideum mimicking intramedullary spinal cord tumor
Journal of Neurosurgery: Pediatrics, Volume 8, Issue 4, Page 363-366, October 2011.

The authors present the cases of 2 patients whose initial clinical presentation and MR imaging findings were suggestive of an intramedullary neoplasm, but whose ultimate diagnosis was determined to be cervical spine instability and cord injury due to os odontoideum.
