I won't try to rank the neuropath programs, but will describe UPenn which I think is very good training. Between HUP (adult) and CHOP (peds), we have seven neuropathology attendings (Rorke, Gonatas, Trojanowski, Mourelatos, Schlaepfer, Golden, Judkins). I believe five of them have served as president of the AANP - which speaks to their reputations. We have people in the WHO books, faculty with successful NIH funded laboratories, etc. etc.
We are also getting two additional neuropathologists to join CHOP, and are working out the details on one if not two neuropathologist to join HUP. Admittedly, our HUP faculty have focused more on neurodegenerative diseases than tumors, but the new hires should change this.
The fellowship may not be for everyone. It's a "sink or swim" type of fellowship where you're given a lot of responsibility quickly.
We have a very interesting neuro-onc service. We get tons of brains via the Alzheimer's disease center. Our muscle/nerve service is picking up, and indeed because National Children's has lost their neuropathologist - their muscle biopsies are now going to come up here. We don't see too much eye path, but fellows have rotated with the opthopath guru at Will's Eye Hospital just down the road (Ralph Eagle).
Anyway, I don't know the criteria for ranking neuropath programs, but when I had the choice, I picked Penn.
