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.

Nice case. Thanks a lot for the pictures! Best, Martin
My 19 yr old daughter has just been diagnosed with CAPNON after presenting with a seizure. 25 doctors later and they are still not sure what course of action to take.'I want them to take a biopsy but they can't all seem to agree as this is the first case they have ever seen. How can I find someone who has treated a patient with CAPNON?
