Abstract
Papillary glioneuronal tumor (PGNT) is a rare central nervous system neoplasm. Of reported cases, the vast majority are located in the frontal and temporal lobes. We present the case of a 39-year-old male who presented with a one day history of gait disturbance following chemotherapy treatment for metastatic rectal adenocarcinoma. Following MRI of the head showed a tectal mass. Following an occipital interhemispheric craniotomy for tumor resection, final pathology was diagnostic of a papillary neuroglial tumor, WHO grade I. To the best or out knowledge this is the only report of it arising from the tectal plate.
