MRI question/Syrixs

2009 MRI.
No fractureFractures across a growth plate or destructive bone lesion . No large disc hernitation identified. No evidence of canal stenosis. No obvious
prevertebral or paravertebral soft tissue mass. Best demonstrated on transaxial immaging is a minor syrinx versus prominent central canal which involves the mid to lower thoracic cord. The sagittal imaging was largerly degraded by CSF pulsation artefact. The region of the conus is intact.
Conclusion
Suspicious for a syrinx extending from approximately T5-T9 although this could also represent a prominent central canal only. Sagittal imaging is somewhat degraded by CSF pulsation artefact. There is no evidence of focal disc herniation, canal stenosis or intramedullary tumour.
There has been no significant change since prior MRI.
The question is ,
No large disc hernitation identified . -  can this mean that there is a small one? this is confusing
Is this a syrinx? if there is no significant change how it is possible that the syrinx is now visible on the level of T5-T9
versus T3-T9 on previous two scans, does it mean that it is getting smaller or there was a problem with MRI.
What does it mean - Sagittal imaging somewhat degraded by CSF pulsation artefact?

I would appreciate if a Doctor could shed some more light on this report.
