Chordoid Glioma, WHO grade II in a 63-year-old male presenting with disequilibrium and hypothermia

Papillary Glioneuronal Tumor, WHO grade I, in a 33-year-old female

Anaplastic Gangliocytoma in the frontal lobe of a 35-year-old female

This is the latest in several resections and follows two rounds of chemotherapy. Immunomarkers positive for neurofilament, and negative for S100, GFAP, synaptophysin, chromogranin, NeuN, HMB45, and MelanA.

Anaplastic Gangliocytoma (note the necrosis in the lower right corner)

Colloid cyst of the third ventricle

Modified by compressive atrophy, the cyst lining cells would otherwise be columnar with obvious cilia

A different area of the same cyst which more clearly demonstrates cilia

There is a neuropathology museum in Lima, Peru

The Institute of Neurological Science (INCN) in Lima  houses the only "Brain Museum" in Latin America. The  collection contains over 3000 samples from which around 300 are on permanent display, including brains with diverse cerebral diseases and anomalies as well as fetal brains with abnormalities.  Unique photomicrographs and other items are also on display.
