Basilar artery dolichoectasia is defined as an increase in the caliber and length of the basilar artery. This phenomenon has been associated with hypertension, arteriosclerosis, decreased arterial elastic properties, arterial wall fibrosis, syphilis, and Marfan syndrome.1 It has been responsible for causing neuro-otologic complaints, including vertigo, tinnitus, sensorineural hearing loss, glossopharyngeal neuralgia, trigeminal neuralgia, and HFS.2- 5 It is believed that the enlarged, ectatic basilar artery (vascular loop) impinges on the involved nerve, resulting in a neurovascular compression syndrome.
