In this work a series of six patients with ventricular tumors located in the lateral or third ventricle, that required conversion from neuroendoscopy to microsurgery, is described. Patients age was 58.8 years average and the tumors were 17.8 mm size`s average. Conversions were necessary due to technical problems and tumor characteristics. The initial neuroendoscopic access was enlarged by extending the skin incision and performing an open craniotomy from the endoscopic burr hole. The ventricular system was reached using microsurgical technique through the neuroendoscopic trajectory. The initial approach technique for patient preparation and the technique used for conversion were easy to perform, bypassed neuroendoscopic complications and allowed tumor resection in all patients of this series. The mean duration of postoperative follow-up was approximately 104 months and no recurrence of the tumor was observed. The possibility of adapting the method to other tumor locations may be considered.
