N2 - Background. Intraventricular neoplasms are rare tumours (1% of the tumours of the central nervous system). The surgical approach sometimes is quite difficult, particularly in the dominant hemisphere. The best choice of surgical approach is discussed. Methods. The authors describe a series of 25 patients who underwent surgical treatment for tumours situated in the lateral ventricles of the dominant hemisphere. They discuss the most influential factors in the choice of surgical approach, which must allow maximum exposure of the lesion and vascular feeding branches without damaging highly functional areas (motor, visual and language areas). In particular, they report their experience using a low transtemporal route, between the middle and inferior gyri, for removing tumours localized in the temporal horn and/or trigone which made it possible to keep post-operative visual and phasic deficits to a minimum. Results. In 5 patients the approach was transfrontal, in 10 temporal, in 6 superior parieto-occipital and in 4 transcallosal. Three patients died. Only 5 patients presented permanent deficits (anomia, apraxia and visual fields alterations). Conclusions. The size, site, hemisphere and vascularization of intraventricular tumours influence the choice of surgical approach. The basal transtemporal approach is particularly indicated to remove tumours of the temporal horn and trigone and it seems to reduce the risk of speech disturbances and alterations of posture.
