Thoracic leminectomy - Intradural arachnoid cyst
on 04/02/2009 a thoracic (hemi)laminectomy was performed at T3-T4.
The reason was a large intradural arachnoid cyst with spinal cord compression, blocking of the CSF fluid, strong back pain, neurologic deficits.
After the surgery I felt much more better, although I had a spinal hygrome for many weeks.
Underhttp://www.dettmann.net/images/th.sagittal.090421.01.png andhttp://www.dettmann.net/images/th.axial.090421.01.png you can see the results post-operative.
About the level of T3-T4 the spinal cord had an anterior-posterior diameter up to 6.5mm.
Since months again I got growing back pain, I feel high pressure in the back and head, and now I have a spinal ataxia, mild neurologic deficits.
The new MRI from 05/27/2010 underhttp://www.dettmann.net/images/th.sagittal.100527.01.png andhttp://www.dettmann.net/images/th.axial.100527.01.png shows us a spinal cord compression, the current diameter has about two thirds of the previous diameter.
Furthermore there is a dural sac herniation through the bone defect from the laminectomy.
In the internet I can't found cases with such images.
Has anyone seen anything like this?
Is then more known about this defect?
