Endoscopic endonasal transplanum transtuberculum resection of a large solid choroid plexus papilloma of the third ventricle.
Choroid plexus papilloma (CPP) is a highly vascular solid or mixed solid-cystic tumor. Previously described resection techniques for the more common solid CPP in the third ventricle have all been through the transcranial route. The authors review the literature and describe a patient who, to their knowledge, is the first successful resection of a large, completely solid CPP of the third ventricle through an entirely endoscopic, extended transphenoidal approach. Using modern neuroendoscopic methods and closure techniques, a gross total resection was accomplished and a successful closure without postoperative cerebrospinal fluid leak was achieved despite the presence of preoperative hydrocephalus. For appropriately selected lesions, an extended endonasal skull base resection can be performed successfully for vascular tumors despite the presence of preoperative hydrocephalus.
