Since the early unsuccessful attempts to remove pineal tumors by Brunner (quoted by Rorschach1) in 1913 and by Puussep2 in 1914, operative approach to these deeply seated, yet often relatively benign, growths has been by two main routes. The first of these was described in great detail by Dandy.3 By this method the pineal region is exposed from above by separating the posterior portion of one cerebral hemisphere from its venous attachments to the sagittal sinus, retracting the hemisphere outward and then incising the caudal end of the corpus callosum (fig. 1). The second method is that described by Van Wagenen.4 This consists in a transventricular exposure of the area in question by an incision through the right occipital region down to the posterior part of the dilated right lateral ventricle, after which the medial wall of the ventricle is incised and the growth disclosed (fig.
