Third ventricular choroid plexus papilloma: a pure neuroendoscopic approach

Pure endoscopic technique in resection of intraventricular tumors is an emerging technology. This case demonstrates resection of a multicentric choroid plexus papilloma in a 2-month-old child. This child had two district tumors: one located in the left atrium and another in the third ventricle. Initial microsurgery was performed to resect the left atrial tumor. With the tumor noted to be not very vascular at initial surgery, the third ventricle tumor was resected with a GAAB neuroendoscope and NICO Myriad. A gross-total resection was achieved. At 3 years' follow-up, the child remains tumor free and developing without any functional deficits. The video can be found here: https://stream.cadmore.media/r10.3171/2023.1.FOCVID22145.
