Efficient endoscopic surgery in cases involving small ventricles is difficult but
possible. The authors describe a neuroendoscopic sheath that has been improved to
make it suitable for use with a Leksell stereotactic frame, which enabled us to accurately
insert a stereotactic needle into the small ventricle and provided an adequate surgical
corridor. A biopsy was performed on a 6-year-old girl who had a primary central nervous
system lymphoma in the pineal body without hydrocephalus.
