Transverse T2 (a) and T1-weighted images at C2 (b), a sagittal T2-weighted image (c) and T1-weighted image after the intravenous administration of gadolinium (d), of the cervical spine. During the MR imaging, the lesion exhibited a lobulated lesion expanding over the entire lamina and pedicles of C2 with the tumor protuberant to the adjacent soft tissue ((a) and (b)). The mass was low-intensity on T1-weighted images and had heterogeneous low and high-intensities on T2-weighted images, suggesting the presence of mineralized and nonmineralized matrices. Gadolinium-enhanced T1-weighted fat saturated images showed intense peripheral and lobulated rim enhancement, whereas lesions with limited mineralization may appear with homogenous enhancement (d). MRI also showed the epidural extension of the mass at the C2/3 level (c).
