Presentation
Low backache with intermittent paresthesia in both legs (left >> right)
Patient Data
MRI showing a well-defined oval lesion in the extramedullary and intradural space in the dorso-lumbar region, compressing and displacing the cord in the right lateral aspect with typical fat signal intensity.
No post-contrast enhancement noted.
No extradural extension noted. No abnormal cord signals or vertebral anomalies were noted.
The oval lesion in the extra-medullary and intradural space on the left lateral aspect of the cord, adjacent to the D12-L1 vertebra with distal extension along the dural space.
The lesion is a T1 hyperintense signal, a T2 heterogeneously hyperintense signal with signal drop on T1FS and STIR images and no post-contrast enhancement.
Case Discussion
Typical findings of Intradural-extramedullary fat containing lesion (lipoma) illustrated through this case.
