Hong Kong J Radiol 2006;9:24-7

Chondroblastoma of the vertebra is a rare condition. Only 26 cases have been reported in the literature; almost all of them involved the anterior and posterior component, with the exception of 1, which involved only the anterior element. There has not been a report of isolated involvement of the posterior element. Clinical presentation with tetraparesis has only been reported in 1 patient, with the majority of patients presenting with non-specific pain at the site of lesion or, occasionally, radiculopathy. This report is of a 39- year-old man with chondroblastoma involving the posterior element of the cervical vertebra, who presented with tetraparesis.
