Here you go edensvision. I've tried to simplify the findings and added some great references that explain things better than I can. I hope it helps.

Impression:
1) Moderate severe right neural foraminal stenosis c4-5 which was also noted in the previous study 1/2011 & is unchanged in the interval

There is a narrowing in the spine, (can be the result of a bulging disc, torn disc, osteophyte, or many other conditions) in the neck at level C4-5 (around the middle of your neck), but it was there on your last check and hasn't changed since then.

2) Moderate thickening of the right nerve root c6 with a surrounding fluid may represent neuropathy. This waas not visualized in the previous study.

The nerve roots arise from the spinal cord and pass out between the discs of your spinal column. Your's has thickened at C6, which is a new finding. They say it might be caused by neuropathy, which is a collection of disorders that occurs when nerves of the peripheral nervous system (the part of the nervous system outside of the brain and spinal cord) are damaged.

3) A small extradural meningeal cyst posterior to the left nerve root c6 with displacing the nerve root anteriorly.

extradural means outside of the spinal canal

meningeal refers to the membrane around the spinal canal

There is a small cyst almost at the bottom of your neck (C6) sitting on the spinal canal's external membrane, close to where the nerve exits between the dics. It's not pressing on the nerve from the front view.

4) Anterior spinal fusion c5-c7. Good alignment of the vertebral bodies.

Your spinal fusion is evident and looks good.

5) Degeneration/desiccation of the intervertebral discs level c3-4, c4-5,c7-t1

There's disc wear visible in most of your neck. Degeneration is usually caused by arthritis

6) other findings as above.
