Cervical spine involvement in metastatic colorectal carcinoma.

Bone metastasis in colorectal carcinoma is an uncommon occurrence. The lumbar and thoracic vertebrae are the most commonly reported sites. In contrast, the reported incidence of cervical vertebral involvement is relatively rare at 2%-7%. We document seven patients with colorectal carcinoma who presented with symptomatic cervical spine metastases and describe their clinical characteristics. This represents a disproportionately large number (24%) of those with bone metastases seen at this centre.
