Inferior altitudinal hemianopia associated with a tumor in the posterior fossa: report of a case
1984
Altitudinal hemianopias may be related to chiasmatic involvement. A case in which horizontal inferior hemianopia is associated with a tumor in the posterior fossa producing a triventricular hydrocephalus is described. The visual field defect is interpreted as a consequence of the pressure by a dilated third ventricle upon the chiasmatic area.
The Transcallosal Anterior Interfoniceal Approach: A Microsurgical Anatomy Study
2014
Objectives: A plethora of surgical strategies have been described to reach deeply lesions situated within the third ventricle, including the Rosenfeld or anterior transcallosal interfoniceal approach (TAIF). Firstly, introduced in 2001, it consists of a small callosotomy followed by the midline transseptal dissection of fornices to enter the roof of the third ventricle. The aim of this microsurgical anatomy study is to describe and show each stage of the surgical procedure, focusing on the possible trajectories to anatomic landmarks. Participants: A total of twenty adult cadaveric specimens were used in this study. Using x3 to x40 magnifications the surgical dissection was carried out in a …
