MRI - MRI Lumbar Spine
What are possible differentials for this lesion?
Differentials are not broad for the appearances of this lesions, and basically, include myxopapillary ependymoma and nerve sheath tumour (e.g. schwannoma).
There is a well-defined spinal canal solid mass at the levels of L2 and L3 that demonstrates low T1 and high T2 signal, and vivid contrast enhancement. This lesion appears intradural splaying the cauda equine nerve roots laterally. No signs of internal calcifications or haemorrhage. There is no expansion of the spinal canal or signs of scalloping over the posterior columns of the vertebral bodies. The intervertebral foramina are capacious and not involved. The remainder of the lumbar spine appears unremarkable.
