Here is what my results were from my CSF flow test. I hear some people talking about the percentages of their blockages and they get very specific on these forums. I asked my neurosurgeon if he could tell me the exact percentage of the blockage and he basically said that the MRI just gives us a snapshot at one point in time of the flow. The flow may be slightly worse or better at other points in time. There really is no way to give an accurate percentage of flow. Is this true? What do you think of my results? I am having a posterior fossa decompression with the dura patch on May 8th.
The MRI CSF flow did demonstrate that there was decreased flow caused by the Chiari malformation. You can see the impression below
1. There is 11 mm tonsillar herniation through the foramen magnum consistent with Chiari I malformation.
2. Altered flow dynamics within CSF dorsal to the cervical cord when compared to the CSF ventral to the cervical cord due to cerebellar tonsillar herniation. There is mild decreased CSF flow in the dorsal foramen magnum secondary to the low bilateral cerebellar tonsils.
