Abstract: Since 1953, when Dobos described a craniopharyn-gioma wholly located in the third ventricle for the first time , there have been a few additional cases which were diagnosed at necropsy, proving the undoubted existence of this particular and rare location. In these necropsy brain specimens the tumor was hidden from outside view, and the third ventricle floor was intact[7, 8, 13, 14, 19, 33, 34, 45–47, 57]. They were named intraventricular craniopharyngiomas (IVC). Their topo-graphical location challenged the embryological theory about craniopharyngioma development, since there was no obvious pathway ascent of Rathke’s pouch-derived epithelial cells to the third ventricle cavity.
