Dolichoectasia is a term used to describe marked widening, tortuosity and elongation of an artery. Intracranial vertebral and basilar arteries are most commonly involved. Vertebrobasilar dolichoectasia is usually asymptomatic. Cranial nerve compression and cerebral ischemia findings are frequently seen in symptomatic patients. However, vertebrobasilar artery dolichoectasia with internuclear ophthalmoplegia (INO) clinical presentation has not been reported in literature yet. In our case, we report of a 67 year old female who had symptoms of diplopia, left abducens palsy and headache with no prior medical or family history of cerebrovascular disease. She has been presented with INO due to left vertebrobasilar dolichoectasia. Atypical presentation of INO is rare and vertebral artery dolichoectasia as the underlying aetiology, like in our case is even rarer and has not been seen in literature so far.
