Brain Invasion

Being visual people, Rob and I always get copies of Evan's MRIs and look at them with our untrained eyes. It used to be we had no idea what we were looking at, but Evan's most recent MRIs are pretty dramatic and it's pretty easy to find what we're looking for. Since I have the CD of MRIs, I thought I'd share these really freaky pics of Evan's head...

After the first surgery, Dr. Weiner inserted a depth probe to about the middle of Evan's brain, where the two sides divide. He inserted grids on the surface of the brain too, but the depth probe goes in much deeper and has 8 points on it that collect seizure info. The advantage is that it is getting information from deep inside Evan's brain instead of from the surface. This was extremely important in Evan's case because Evan had three tubers in this area and Dr. Weiner was able to put the probe through all three. The probe ended in the tuber deepest in and this is where the seizure activity was originating in Evan's brain. Up until this trip, every doctor thought the seizure activity was coming from the largest tuber closest to the surface. The image below is of the depth probe in Evan's brain after the first surgery. The white area close to the center of the brain (where the depth probe ends) is the tuber causing all the trouble.


After the second surgery another MRI was done and you can see the area removed in the image below.


If you look really close, you can see a depth probe on each side of the area removed. They go deeper than what you can see in this image and are picking up additional seizure activity. The final surgery will be to remove a little more brain tissue to eliminate the rest of Evan's seizures and remove all the grids and probes.

The crazy thing is that Evan is completely normal after having this much of his brain removed. His spirits are effected by all this brain invasion, but you'd never guess by talking to him or interacting with him that he just had two pretty major brain surgeries.

Lisa,
WAY cool images. I'm one of those freaky people who loves the nitty gritty of medical stuff. Doug & I have kept up with your every posting and have been sending our best vibes to Evan and all of you. We are in awe. Hang in there, you & Rob are rock stars too in our book!!

Very cool. I am fascinated by the brain and amazed at what doctors can do.

I'm so glad Evan is feeling happier. We'll be crossing our fingers for early OR space.

I'm with Wendy. . ."WAY cool images"! Thanks for posting these pictures! I'm glad you're working with a surgeon you trust, and that Evan is providing him the information he needs to do his job well.

Love to all of you!

An outstanding share! I have just forwarded this onto a colleague who was doing a little homework
on this. And he actually bought me breakfast due to the
fact that I discovered it for him... lol. So allow me to reword this.
... Thank YOU for the meal!! But yeah, thanx for spending time to talk about this issue here on your web site.
