Preoperative MR images of the lesion measuring 28 mm x 43 mm x 21 mm. (a and b) Sagittal T1-weighted images with gadolinium enhancement. Avid, heterogeneously enhancing lesion extending from T3 to T5. (c) Coronal T1-weighted images demonstrating tumor displacing the cord to the right with cord signal change. (d) Axial T1-weighted image. Lesion demonstrating homogenous low signal. (e) Axial T2-weighted image. (f) Axial T1-weighted image.

Further, the calcification seen on CT, and lack of bony destruction was consistent with a benign lesion [Figure 1].
Photomicrographs of the specimen. (a) Meningioma infiltrating through dura (H&E, x100). (b) Meningioma infiltrating through fibrous dura with prominent psammomatous calcifications (arrowhead) (H&E, x200). (c) Intranuclear pseudoinclusions (demonstrated by arrowheads) and typical meningothelial morphology (H&E, x400).
