Plasmacytoma. Sagittal and axial MR images demonstrate an expansile mass (orange arrows) arising from the posterior elements of C2 and C3. The mass demonstrates hypointense signal to normal marrow on T1 (a), and isointense to hyperintense signal on T2 (b). Post-contrast sagittal T1 (c) and axial T1 fat-suppressed (d) sequences demonstrate enhancement. A few areas of curvilinear low-signal intensity are seen at the remaining thickened bony cortex (white arrows), projecting into the lesion, resulting in a “mini-brain” appearance resembling cortical sulci
