Endoscopic endonasal transplanum transtuberculum resection of a large solid choroid plexus papilloma of the third ventricle

Disseminated choroid plexus papillomas in adults: A case series and review of the literature

Choroid plexus papillomas (CPPs) are uncommon, usually intraventricular, low-grade tumors, accounting for less than 1% of all intracranial neoplasms and 2-4% of brain tumors in children. Dissemination of CPPs to multiple levels of the neuraxis has been seldom observed. Thus far, only 26 adult patients have been reported in the English language literature. With some exceptions, disseminated CPPs have been observed in adults and involved multiple sites along the cerebrospinal fluid pathways. Occasionally, intraparenchymal extension has been documented, and secondary involvement of the suprasellar region has been reported in only five patients. Postoperative treatment of CPPs has not been standardized. Most recommended therapies have been extrapolated from a series of atypical papillomas or carcinomas of the choroid plexus in children. We herein report a series of three patients of disseminated choroid plexus papillomas providing additional insights into this relatively rare entity.

Microsurgical resection of tumors of the lateral and third ventricles: operative corridors for difficult-to-reach lesions

Tumors of the lateral and third ventricles are cradled on all sides by vital vascular and eloquent neural structures. Microsurgical resection, which always requires attentive planning, plays a critical role in the contemporary management of these lesions. This article provides an overview of the open microsurgical approaches to the region highlighting key clinical perspectives.
