Presentation

Back pain and lower limb weakness

Patient Data

Age: 45 years
Gender: Male
MRI

There is an intradural extramedually lesion at the level of T12. This is low signal on T1, Low signal on T2 and demonstrates no enhancement post-contrast. 

Appearances are in keeping with an intradural sequestered disc fragment. 

This was confirmed at surgery. 

Case Discussion

Intradural disc herniations are rare and can be difficult to differentiate from other intradural extramedullary lesions. The key finding is that lesion should have a similar appearance to disc on all sequences. 

In this case, despite being reported as an intradural disc fragment, at surgery the dura was not opened and no disc fragment was identified. A repeat scan showed the disc fragment unchanged and at repeat operation the dura was opened and a disc fragment was removed.
