P418: GROSS TOTAL RESECTION OF A COMPLEX RIGHT CEREBELLOPONTINE ANGLE TUMOR WITH THE HELP OF NEURO-ENDOSCOPY
Amanda Roehrkasse, MD, PhD1; Samir Sur, MD2; 1National Institutes of Health; 2Medstar Georgetown University Hospital

A 63 year old male presented with a complex right cerebellopontine mass manifested by headaches, hearing loss and syncopal events. A right retrosigmoid craniotomy revealed a keratin filled cystic structure adherent to the eighth cranial nerve. The lesion was removed with careful sharp dissection and preservation of cranial nerve eight and the labyrinthine artery. Neuro endoscopy allowed for gross total resection of the complex mass found to be a mature teratoma on final pathology.
