User avatar Hi Jhbman,

Unfortunately, I probably won't be of too much help to you in this but I'll tell you what I know.

I am uncertain what the significance of the periventricular white matter changes is.. This may indicate something such as multiple sclerosis; however, I am not certain.

The mucous retention cysts are a common finding (around 2 per 1000 people). They are generally harmless although occasionally they can be large enough to cause blockages of the nose.

The findings related to the shunt are also likely normal.

My best advise would be to discuss these findings with a neurologist to see if there is anything concerning.

Best wishes.
