Cranial Location
Intraventricular
Intraventricular lesions arise within the lateral, third or fourth ventricles and often present with obstructive hydrocephalus rather than a focal deficit. Access requires a transcortical or interhemispheric transcallosal corridor chosen to spare eloquent cortex and the deep veins.
Common entities include colloid cysts, central neurocytomas, ependymomas, subependymomas and choroid-plexus tumours. Endoscopic techniques increasingly address both the lesion and the obstructed CSF pathways in the same procedure.
