Magnetic resonance imaging of the cervical spine without gadolinium reveals a lesion which is hypointense (arrows) on the T1W sagittal (a) image. The lesion appears lightly hyperintense on the T2W axial (b) and sagittal (c) image with an intradural (star) and extradural (arrow) portion. Both components are enhanced after gadolinium injection on the T1W axial (d) and sagittal (e) image, which expands through the foramen on the T1W coronal image (f) with a dumbbell-shaped pattern.

After gadolinium injection, the whole mass was enhanced and unveiled two portions: intradural and extradural [Figure 1]. T1W with contrast, we noticed a dumbbell-shaped expansion at the left C6-C7 and C7-T1 intervertebral foramen [Figure 1f]. The bone window of the computed tomography (CT) scan revealed calcification inside the lesion [Figure 2].

During the operation, we confirmed that the tumor was macroscopic calcification, located in extramedullary, intra-, and extradural sites [Figure 3].
Histology study of the tumor revealed a psammomatous meningioma. This densely calcified tumor is characterized by the presence of numerous psammoma bodies (arrows). (a): x40; hematoxylin-eosin stain, (b): x100; hematoxylin-eosin stain.
