Presentation
Lower limb numbness
Patient Data
The spinal canal opposite T10 and T11 shows a well-defined, ovoid, dural-based soft tissue lesion in an intradural, extramedullary location, measuring 2.3 x 1 x 1 cm; present at the right anterolateral aspect of the spinal cord, compressing it left posterolaterally. It demonstrates T1 isointensity and T2 slightly hyperintense signal, with moderate post-contrast enhancement. A small related inferior enhancing dural tail is seen. No cystic changes or signal void are noted.
Case Discussion
Features of an intradural extramedullary lesion which can be meningioma, schwannoma or neurofibroma. The possibility of meningioma is based on the homogeneous texture, homogeneous enhancement, absence of flow voids and cystic changes, and the presence of a dural tail. The thoracic spine is the most common site for spinal meningioma.
