Abstract

In this video, the authors present ultrasonic resection of calcified tumor of the third ventricle in a 12-year-old boy. He presented to the emergency department with a 1-week history of headache, drowsiness, and bilateral papilledema. Despite extensive calcification visible on a CT scan, a minimally invasive pure endoscopic approach was chosen. The use of an ultrasonic aspirator allows fast and safe removal of the tumor. The histological diagnosis was a low-grade glioneuronal tumor. In conclusion, the endoscopic ultrasonic aspirator is a useful tool to resect tumors in the ventricular system. The presence of calcifications within the tumor does not contraindicate an endoscopic approach. The video can be found here: https://stream.cadmore.media/r10.3171/2023.1.FOCVID22143.
