The next in our "Best of the Month" series is from November 11, 2016:
Approximately 59 cases of CAPNON have been reported in the literature, A non-neoplastic entity that can be found in either an intra-axial or extra-axial location, the pathogenesis of CAPNON is unclear but a reactive process has been favored. The outcome is generally considered to be excellent, with gross total resection typically curative. This case is somewhat unique in that it harbors adipose tissue.

Hi Brian...it has been quite a while since I looked at your blog, which is why I'm posting in March 2017 about this post from November 2016. I have had two cases of this in the past couple of years. One of our Radiology residents asked to take a slide to the ARP course (formerly the AFIP Radiology/Pathology course).
I have, of course, forgotten my log-in information, so I'll post here as "anonymous", but this is Doug Miller.
