[Oradlist] bilateral neurilemmoma??

[Garnet Packota]

Ken - I do recall that on one of our cases, there was some thinning of 
one of the cortices on the initial images.  Same finding on recall 
images a few years later....Both cases have been lost to further 
follow-up, unfortunately.

I think an MRI for baseline information is a good idea, and followup 
imaging should be done pending the MRI results.
