Vertebrobasilar dolichoectasia is defined as elongation, dilatation, and tortuosity of the basilar and vertebral arteries. We describe two patients with vertebrobasilar dolichoectasia, one who presented with acute posterior circulation infarct and subsequent arterial dissection, and the other who presented with acute posterior circulation infarct, arterial dissection, and hydrocephalus at presentation. These cases serve as a reminder of the clinical significance of the presence of vertebrobasilar dolichoectasia and its potential complications.
