A case of dolichoectasia of vertebrobasilar artery with an obstructive hydrocephalus, due to direct compression on pons and midbrain, which is an extremely rare entity is presented.

VBD should be considered a differential diagnosis for patients presenting with recurrent transient ischemic attacks, such as locked-in syndrome, without any identifiable cause.

Basilar artery dolichoectasia is rare, the otorhinolaryngologist should be aware of vascular causes when evaluating a patient with otoneurological symptoms, and the patient should be diagnosed with basilar arteries dolicoectasia.

In case the diagnosis is made promptly, ideally with the help of an advanced neuroimaging, intravenous thrombolysis, or catheter-based endovascular treatment can be performed immediately to improve prognosis and reduce mortality.

Dolichoectasia is detected in 3% of patients with first cerebral infarction and is associated with better survival but higher rates of stroke recurrence, while there were no significant differences in the following characteristics among those with and without the abnormality.

In patients with VBD, superimposed atheromatous changes of the posterior circulation may have an important role in precipitating ischemia, however, other factors related to the severity of the dolichoectasia also favor ischemIA and in some cases are the only factors responsible.

Current experience and the literature review highlight the usefulness of neuroendoscopy as a diagnostic and therapeutic solution, particularly in cases considered to have obstructive hydrocephalus caused by compression of the foramina of Monro by dolichoectatic basilar artery.

Six patients for whom computed tomography revealed a curvilinear calcific mass anterior to their brainstem were evaluated and magnet resonance imaging and magnetic resonance angiography safely diagnose this interesting arterial abnormality.

Independent factors for developing stroke in VBD patients are clarified and intensive management of these clinicoradiological factors could prevent a stroke event in V BD patients.

The GENIC investigators convincingly show an association between intracranial dolichoectasia and all of the manifestations of penetrating artery-related infarction and white matter disease.

A case of atypical dolichoectasia affecting both circulatory systems as well as the middle and anterior cerebral arteries, with intracerebral haemorrhage is described.

VBD cases had an increased likelihood for PCD, all cause mortality, and reduced cumulative survival independent of other vascular risk factors in this cohort, suggesting that VBD may be an independent risk factor for stroke.

The most important clinical presentations of dilatative arteriopathy include acute brain ischemia; a progressive course related to compression of cranial nerves, the brain stem, or the third ventricle; and catastrophic outcome caused by vascular rupture.
