Unedited microneurosurgery of a large recurrent papillary tumor of the pineal region

摘要

Background:Papillary tumor of the pineal region (PTPR) is a new entity introduced in the 2007 World Health Organization (WHO) nomenclature to describe a rare grade II–III pineal lesion with epithelial-like papillary architecture and particular immunohistochemical features. PTPR is extremely rare in children. Herein, we present an unedited gross total microsurgical resection of a histologically confirmed WHO grade III PTPR. Our aim is to demonstrate the efficiency and safety of our microsurgical technique into deep brain territories under the principle “simple, clean, and preserving the normal anatomy.” For this, a posterior occipital interhemispheric approach and a proper praying sitting position were essential.
