They didn't do cisternogram. They measured the opening and closing pressure and took 4 tubes of spinal fluid and did all the tests on that fluid. Nothing abnormal. I have done only MRI with contrast and no problem. It seems like indium may be more accurate for CSF leaks but with your nursing not sure.

As for as other alternative if you have any fluid leaking from nose they can check it out (my friend did once he had headaches and fluid leaking from nose but it was not a CSF leak). I almost forgot. Once this Neurologist ordered an MRI (I have done quite a few) to check for CSF leak using contrast on my brain.

If I am not wrong one member had increased intracranial pressure and suffered a lot and after lumbar puncture she had tremendous relief. It is a different case than CSF leak but just mentioning.

May be you can go after neck first and then try this procedure?

Sorry I understand this is a tough call.
