“…These VBD patients obtained good therapeutic effects with microvascular decompression treatment 34. In addition, VBD can also compress the abducens nerve 36, trochlear nerve 37, and oculomotor nerve 38. Other nerve compression symptoms such as nystagmus 39, tinnitus 40, hoarseness, and difficulty swallowing 41 have been reported.…”

Vertebrobasilar dolichoectasia (VBD) is a rare disease characterized by significant expansion, elongation, and tortuosity of the vertebrobasilar arteries. Current data regarding VBD are very limited. Here we systematically review VBD incidence, etiology, characteristics, clinical manifestations, treatment strategies, and prognosis. The exact incidence rate of VBD remains unclear, but is estimated to be 1.3% of the population. The occurrence of VBD is thought to be due to the cooperation of multiple factors, including congenital factors, infections and immune status, and degenerative diseases. The VBD clinical manifestations are complex with ischemic stroke as the most common, followed by progressive compression of cranial nerves and the brain stem, cerebral hemorrhage, and hydrocephalus. Treatment of VBD remains difficult. Currently, there are no precise and effective treatments, and available treatments mainly target the complications of VBD. With the development of stent technology, however, it may become an effective treatment for VBD.

“…Cranial nerve neuropathies due to the compression of VBD is a frequent condition, but INO due to the involvement of MLF is generally caused by thrombosis of brain stem artery [13,14]. Even though an ischemic lesion was considered at initial presentation, MRI showed no evidence of ischemia.…”

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.

“…In such cases, diabetes mellitus or hypertension is a possible cause; however, some cases show no potential causes of isolated abducent nerve palsy. [1,2] Recently, patients with abducent nerve palsy due to neurovascular compression have been reported; [3][4][5][6][7][8][9][10][11][12][13][14][15] however, only a few report showed neurovascular compression clearly. Here, we report a patient with isolated abducent nerve palsy induced by neurovascular compression of vertebrobasilar dolichoectasia, which MRI with fast imaging employing steady-state acquisition (FIESTA) and magnetic resonance angiography (MRA) source images clearly showed.…”

If the origin of isolated abducent nerve palsy cannot be found on neuroradiological examinations, diabetes mellitus is known as a probable cause; however, some cases show no potential causes of isolated abducent nerve palsy. Here, we report a 74-year-old male who suffered from diplopia due to isolated left abducent nerve palsy. Magnetic resonance angiography and fast imaging employing steady-state acquisition imaging clearly showed a dolichoectasic vertebrobasilar artery compressing the left abducent nerve upward and outward. There were no abnormal lesions in the brain stem, cavernous sinus, or orbital cavity. Laboratory data showed no abnormal findings. We concluded that neurovascular compression of the left abducent nerve might cause isolated left abducent nerve palsy. We observed him without surgical treatment considering his general condition with angina pectoris and old age. His symptom due to the left abducent nerve palsy persisted. From previous reports, conservative treatment could not improve abducent nerve palsy. Microvascular decompression should be considered for abducent nerve palsy due to vascular compression if patients are young, and their general condition is good. We also discuss interesting characteristics with a review of the literature.
