Does anyone understand what this means?

I finally found the letter I recieved from a NS I saw, was wondering if anyone understands what this means: there is an impediment of CSF flow posterior to the cervicomedullary junction.

I understand that the CSF is being slightly blocked, wondering what the cervicomedullary junction is, and I know you guys are soooooo helpful!

cervicomedullary junction [ser´ vih koh med´ you lair ee] Where the extension of the spinal cord becomes the medulla oblongata of the brain. Posterior would be behind.  I hope this helps.
