Pathology in this region varies; thus, biopsy can be of great value in the management decision making. Appropriate instrumentation remains an area of interest to further advance flexible neuroendoscopic techniques and applications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>The authors report an illustrative case using flexible neuroendoscopy through a single burr hole for simultaneous endoscopic third ventriculostomy (ETV) and tectal tumor biopsy using urological cup forceps in a 13-year-old boy who had presented with obstructive hydrocephalus.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>The authors demonstrate the feasibility of simultaneous ETV and tectal lesion biopsy via flexible neuroendoscopy to address obstructive hydrocephalus and obtain a tissue biopsy in a single-site procedure. They found that the use of flexible cup forceps designed for uroscopy is an important complement to flexible neuroendoscopy. Given the evolving applications of flexible neuroendoscopy, this has implications for instrumentation adaptation and future design.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case22517","type":"journal-article","created":{"date-parts":[[2023,4,18]],"date-time":"2023-04-18T08:48:15Z","timestamp":1681807695000},"source":"Crossref","is-referenced-by-count":5,"title":["Endoscopic third ventriculostomy and biopsy of a tectal lesion using flexible neuroendoscopy and urological cup forceps: illustrative case"],"prefix":"10.3171","volume":"5","author":[{"given":"Meredith","family":"Yang","sequence":"first","affiliation":[{"name":"Pritzker School of Medicine, The University of Chicago, Chicago, Illinois"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Wolfson","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Rush University Medical Center, Chicago, Illinois"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa A.","family":"LoPresti","sequence":"additional","affiliation":[{"name":"Division of Pediatric Neurosurgery, Ann & Robert H.
