RATIONALE: Study reported an extremely rare case of trigeminal neuralgia, vestibular paroxysmia, and hemifacial spasm successively occurring in a patient with vertebrobasilar dolichoectasia (VBD). PATIENT CONCERNS: A 66-year-old female patient presented with episodic vertigo for 20 days before she was admitted to our hospital. Vertigo suddenly occurred when the patient rotated her head 20 days ago, the symptoms of vertigo were improved after continuous 1 to 3 seconds, and similar symptoms were repeated in sleep and rest, with a frequency of 30 to 40 times per day...

Purpose: To report an unusual case of vertebrobasilar dolichoectasia causing both trigeminal neuralgia and ipsilateral sixth cranial nerve palsy. Observations: A patient had undergone surgical decompression of trigeminal neuralgia caused by dolichoectatic vertebral and basilar arteries years before presenting with ipsilateral sixth nerve palsy. Brain MRI showed deviant vertebrobasilar arteries that presumably now compressed the sixth cranial nerve. The unaffected left sixth cranial nerve was visible on MRI, but the affected right sixth cranial nerve was not...

In clinical practice, the vertebral arteries of a patient are often found to be not equal in size and the basilar artery may not be situated in the center. Our observational study showed that vertebral dominance and basilar bending are common, and their occurrence is related to advanced age and hypertension. The right vertebral dominance tends to coincide with left basilar bending, and, vice versa, the left vertebral dominance tends to coincide with right basilar bending. The left vertebral dominance is more common than the right dominance...

Almost all primary hemifacial spasms are associated with one or more neurovascular conflicts, most often at the root exit zone in the immediate vicinity of the brainstem. Imaging has first to exclude a secondary hemifacial spasm and secondly to search for and characterize the responsible neurovascular conflict(s). Magnetic resonance imaging should include high-resolution anatomical hyper T2-weighted sequences and magnetic resonance angiography by using 1.5 or even better 3 Tesla magnets. The most frequent vascular compressions are from the anterior-inferior cerebellar artery, the posterior-inferior cerebellar artery and the vertebrobasilar artery; venous conflicts are very rare...

BACKGROUND: Vertebrobasilar dolichoectasia (VBD) is a clinical entity associated with ischemic stroke, compression of cranial nerves or brainstem, and hydrocephalus. There have been relatively few studies following the progression of VBD in patients presenting with a variety of diverse clinical features. CASE PRESENTATION: Here, we report a case study of a male with progressive VBD who was followed from November 2012 to December 2016. The patient had diagnosed hypertension for several years and suffered from left peripheral facial paralysis, recurrent ischemic attacks in the brainstem and cerebellum, obstructive hydrocephalus and frequent pneumonia...

OBJECTIVES: Vertebrobasilar dolichoectasia (VBD) is a dilatative arteriopathy associated with intracerebral hemorrhage. In the present study, we sought to evaluate the frequency and anatomical distribution of cerebral microbleeds (cMBs) and intracerebral hemorrhage (ICH) in VBD. METHODS: From a MRI database 94 VBD patients were identified and analyzed with special emphasis on cMBs and ICH on T2*-weighted gradient echo images (GRE) in relation to the established diagnostic MRI criteria of VBD (diameter, height, and lateral position)...

Background: Symptomatic hydrocephalus due to vertebrobasilar dolichoectasia is a rare occurrence. Case Description: We report a patient who presented with acute confusion and vomiting. Neuroimaging revealed elongated and tortuous basilar artery indenting and elevating the floor of third ventricle causing obstructive hydrocephalus. Initially, the patient was treated with external ventricular drain and then with ventriculo-peritoneal shunt. Conclusion: We suggest prompt surgical intervention upon diagnosis as a first choice of treatment in order to avoid further complications...

BACKGROUND Vertebrobasilar dolichoectasia (VBD) is a complex progressive arterial disease characterized by dilation, elongation, and tortuosity of the vertebral and basilar arteries, and may be congenital or acquired. VBD may lead to progressive compression of the brainstem, cranial nerve abnormalities, and intracranial hemorrhage, but may also be associated with arterial thrombosis, with ischemic stroke as the most common clinical outcome. CASE REPORT Two cases of VBD are presented, both with acute bilateral ophthalmoplegia and cranial nerve palsies, and vertebrobasilar arterial thrombosis that resulted in ischemic stroke...

Vascular dementia (VaD) is a group of heterogeneous diseases with the common feature of cerebral hypoperfusion. To identify key factors contributing to VaD pathophysiology, we performed a detailed comparison of Wistar and Sprague-Dawley (SD) rats subjected to permanent bilateral common carotid artery occlusion (BCCAo). Eight-week old male Wistar and SD rats underwent BCCAo, followed by a reference memory test using a five-radial arm maze with tactile cues. Continuous monitoring of cerebral blood flow (CBF) was performed with a laser Doppler perfusion imaging (LDPI) system...

INTRODUCTION: We present a rarely seen case of cerebral infarction due to intracranial dolichoectasia coexisting with spontaneous dissection of the basilar artery. A definition of dolichoectasia, its pathology, and imaging findings, as well as the clinical management and prognosis are briefly reviewed. CONCLUSION: We discuss in general terms the diagnosis of basilar artery dissection and its probable relationship with the occurrence of dolichoectasia.

A 73-year-old man was diagnosed with an incidental finding of right homonymous hemianopia and presyncopal spells. Magnetic resonance imaging revealed a vertebrobasilar dolichoectasia (VBD) with compression of the left optic tract. VBD is defined as an elongation and dilatation of the basilar artery. Only a few cases have been described in the literature of VBD causing optic tract compression. So far no treatment option has been described for these cases, while surgical options exist for compressions of other cranial nerves, most commonly the trigeminal nerve...
