Abstract

Intraventricular meningiomas require a cautious surgical preoperative planning in an attempt to avoid unwanted postoperative neurological déficits. Despite that better surgical approaches exist, the posterior parietal transcortical approach to intraventricular trigonal lesions, with its unavoidable damage to the posterior parietal white matter pathways, is still popular in clinical practice, at times,like in the following case report, without any electrophysiological support.
