Small Lateral Ventricle

On my MRI, my NS noted that my lateral ventricles were small. He thought it could be from a pseudotumor or systemic, brain inflammation. I had the bloodwork for the inflammation and it came back normal. I am scheduled for a spinal tap on monday.

I have been scouring the internet for causes for a small ventricle...he said it looked kind of squished, and I cant find anything. I also forgot to ask him what other things could cause my ventricle to look like that.

Do any of you have any ideas, other than a pseudotumor, that can cause such a thing?

thanks so much for your replies

Hey Beeba....

he is doing the tap to check for pressure and confirm or rule out a pseudotumor.

what is an mra and mrv?

I too have very small ventricles. I do have pseudotumor cerebri (intracranial hypertension). After decompression, 6 mos, later I had to have a shunt put in. I have a VP shunt and my surgeon had to actually drill to make the ventricle bigger because that is where the shunt needed to go into the brain to drain off the excess fluid. Now the sugeon does not like to adjust my shunt to drain faster because that makes your ventricles smaller and said he doesn't want mine to be any smaller than they already are! I don't know if this helps or not :)

Oh and I never had an mra or mrv done. Just MRIs (lots).

Hi Carla

how did your symptoms respond to both the shunt and the decompression surgery? Should the shunt have been done first to see if your symptoms got better? Did you try Diamox also? How do you feel now? The surgeon drilled the ventricle in your brain?????

Everything I have read says the Lateral Ventricles develop embryologically derived from the centre of the neural tube (the neural canal).

So it is a congenital defect.

.

This gives great information on the Ventrical System. I actually learned a lot about the brain from this description.

I wish I could help more.

I was better after the decompression, but as the fluid built up again over the next 6 months, I began to have headaches again. When the doctor went out to talk to my husband right after my decompression, he told him that he thought that I was going to be in the 20% who would need a shunt. I have felt better since I got the shunt. That was 4 years ago in November.

The neurosurgeon widened the openig in my skull to allow for the VP shunt.

Thanks, Tracy. This is very informative. I appreciate it and am going to save this one for sure :)
