Osteochondroma of the cervical spine MR findings

We report two cases of osteochondroma in the region of the cervical spine. The magnetic resonance (MR) images well demonstrated the relationship of the tumor, the spinal cord, and adjacent soft tissue, but correct diagnosis by MR imaging was difficult in one patient due to unusual gadolinium enhancement. Computed tomography played an important role in these patients by demonstrating the exact origin and nature of the tumor.
