Visual Loss, Homonymous Hemianopia, and Unilateral Optic Neuropathy as the Presenting Symptoms of Vertebrobasilar Dolichoectasia

Vertebrobasilar dolichoectasia (VBD) is a relatively rare disorder for which unfortunately there is no treatment. Here we describe a case of simultaneous pre- and postchiasmal visual pathway pathology secondary to a space occupying VBD. In addition our patient demonstrates one of the very few cases of VBD compression of the retrochiasmal pathway with no other cranial nerve involvement.
