Abstract
A 51-year-old woman presented with nonradiating back pain since 7 years ago and progressive spastic paraparesis since 2 years ago. Magnetic resonance imaging (MRI) of her spine (Fig. 1) showed a 1.5 × 1.9 × 1.4 cm sized, well-defined, intradural extramedullary lesion at the level of D10 vertebra. It was dorsally located and had compressed the cord ventrally. It was isointense to the cord on T1- and T2-weighted sequences and demonstrated homogeneous contrast enhancement. There was a “dural tail” sign noted in the dorsal dura. Following laminectomy, a calcified lesion arising from the dorsal dura was encountered (Fig. 2) and excised en-bloc along with the involved dura. Histopathological examination revealed the lesion to be a psammomatous meningioma (WHO grade I).

The thinned out cord (open arrow) is seen rostral to the upper pole of the lesion. (Right) The gross appearance of the calcified lesion. View Large Image Figure Viewer Download Hi-res image
