The video describes the surgical approach performed to achieve the partial removal of an optic pathways glioma in a 17-month old baby presenting with gait disturbances and torticollis. The prevalent cranio-caudal expansion of the tumor, the presence of a large ventricular dilatation that dictated the necessity to open both foramens of Monro to restore CSF circulation, and above all the presence of the septal cyst, contributed to the choice of the transcallosal-transeptal-interforniceal approach. The different steps of the procedure are described: interhemispheric dissection, identification and dissection of pericallosal arteries, Callosotomy, identification of the cyst of the Septum Pellucidum, vertical progression within the cavity of the septal cyst, identification of the thela chorioidea and of the two components of the fornix, coagulation of the thela, identification and dissection of the internal cerebral veins, entry into the third ventricle, dissection of the tumor from the third ventricle ependyma, internal debulking of the tumor until removal of approximately 70% of the tumor volume remaining above the hypothetic plan of the optic pathways.
