The patient went on to have a resection, which confirmed the diagnosis of a spinal meningioma . 

Histology

Paraffin sections show a moderately hypercellular meningioma. This has a well-developed syncytial architecture. Many calcified Psammoma bodies are also present. Tumor cells have uniform nuclear features. No mitotic figures or areas of necrosis are seen. Dural attachment is noted.

Final diagnosis: Meningioma (WHO Grade I - transitional / mixed histology).
