Cervical Spinal Meningeal Melanocytoma Presenting as Intracranial Superficial Siderosis

Figure 2

Sagittal sections of the cervical vertebral column: (a) T2 weighted and (b) T1 weighted images showing an intradural extramedullary mass which appears hypointense on T2 weighted image and hyperintense on T1 weighted image. (c) Postcontrast fat saturated T1 weighted and (d) subtracted contrast image showing mild peripheral heterogeneous enhancement of the tumor since the true enhancement pattern was obscured by the strong T1 hyperintensity of the mass on unenhanced images.
