Hydrocephalus

and

peritumoral edema caused by a tumor in the ventricle were seen at admission (B). The ventricle

size was normalized after ventriculoperitoneal shunt placement (C). The tumor was displaced

beyond the ventricular midline five months later (D). Half of the tumor was resected during the

1st surgery using the trans callosal route (E) and the remaining mass was removed during the

second surgery using the trans inferior temporal sulcus approach (F).
