A Novel Diamond-Shaped Anatomical Model to Learn the In Vivo Endoscopic Anatomy of the Posterior Third Ventricle

Digitally enhanced illustrations of low-resolution images developed from early observations with first-generation fiberscopes validated the endoscopic geometric appearance of the posterior third ventricle as a diamond. The diamond model presented is a useful educational tool for learning and understanding the anatomy of the posterior wall of the third ventricle.
