INTRODUCTION: Dolichoectasia of vertebrobasilar artery is a rare vasculopathy, which is characterized by ectasia, elongation, and tortuosity of the basilar artery. CASE DESCRIPTION: A 85-year-old man was referred to the Clinic of Neurology with sudden-onset coma. A brain computed tomography scan showed remarkable fusiform dilatation with elongation of basilar artery, with compressive effect on brain stem. Autopsy confirmed existence of vertebrobasilar dolichoectasia, with organized old thrombus and partially with recent occlusive thrombosis...

Little literature is available on hemiparesis caused by vascular medullary compression, which may occur as a result of dolichoectasia of the vertebrobasilar arterial system. In this paper, we report a case of vertebral artery compression of the medulla oblongata in a 67-year old woman. The patient was hypertensive and developed hemiparesis and intermittent spasms for five years, which became worsened for one year. Cranial nerve MRI showed compression of the medulla oblongata by the left vertebral artery. Motor evoked potential (MEP) examination showed abnormal conduction of MEPs of bilateral toe abductors...

BACKGROUND: Basilar artery (BA) dolichoectasia has been associated with cerebral small vessel disease (SVD). However, studies have focused on stroke patients, and results cannot be extrapolated to the population at large. In this study, we aimed to assess prevalence of BA dolichoectasia and its association with SVD in community-dwelling older adults living in rural Ecuador. METHODS: Atahualpa residents aged ≥60 years underwent brain magnetic resonance imaging and magnetic resonance angiography of intracranial vessels...

An increased diameter (ectasis) and/or long and tortuous course (dolichosis) of at least one cerebral artery define intracranial arterial dolichoectasia (IADE). IADE could be detected incidentally or may give rise to an array of neurological complications including ischemic stroke, intracranial hemorrhage, or compression of surrounding neural structures. The basilar artery is preferentially affected and has been studied in more detail, mainly due to the presence of accepted diagnostic criteria proposed by Smoker and colleagues in 1986 (1)...

BACKGROUND AND PURPOSE: Cervicocephalic dolichoarteriopathy is not rare in patients with acute stroke. Results of intravenous (IV) tissue plasminogen activator (tPA) treatment have not been documented in this specific population. METHODS: One hundred (58 females, age: 69 ± 13 years) consecutive patients treated with IV tPA for acute anterior circulation stroke were analyzed. Smoker's criteria were used to score basilar artery dolichoarteriopathy and combined criteria of Weibel-Fields and Metz for cervical carotid artery dolichoarteriopathy...

Late-onset Pompe disease (LOPD) is an adult type of classical Pompe disease and presents without cardiomyopathy. Neuroimaging in LOPD is typically limited to posterior circulation and involves dilative arteriopathy, especially dolichoectasia and intracranial aneurysms. We report an interesting case of an established diagnosis of asymptomatic LOPD in a young man with a restrictive-variant pattern in posterior vasculature. We discuss the clinical presentation, neuroimaging, existing literature, and prognosis in vascular variants of LOPD...

Vertebrobasilar dolichoectasia (VBD) is characterized by significant dilation, elongation, and tortuosity of the vertebrobasilar system. We present a unique case of VBD, confirmed by neuroimaging studies, showing vascular compression of the right optic tract and lower cranial nerves leading to an incongruous left homonymous inferior quadrantanopia and glossopharyngeal neuralgia.

BACKGROUND: The aim of this study was to analyse the morphometry of the intracranial segment of the vertebral artery in the context of clinical usefulness. The results were compared with published data available in full-text archived medical journals. MATERIALS AND METHODS: More than 100 DSA (digital subtraction angiography) and 3D angio-CT (computed tomography) examinations were used to measure the following parameters: the whole and partial length of V4 in characteristic anatomical points, the diameter in three places (on the level of foramen magnum, in point of exit to the PICA, and in the vertebro-basilar junction), the angle of connection to the VAs, and all anatomical variations including fenestration, duplication, dolichoectasia or absent artery...

BACKGROUND AND PURPOSE: Among patients with vertebrobasilar dolichoectasia is a subset of patients with disease affecting the anterior circulation as well. We hypothesized that multivessel intracranial dolichoectasia may represent a distinct phenotype from single-territory vertebrobasilar dolichoectasia. The purpose of this study was to characterize clinical characteristics and angiographic features of this proposed distinct phenotype termed "diffuse intracranial dolichoectasia" and compare them with those in patients with isolated vertebrobasilar dolichoectasia...

A 78-year-old man was admitted to our hospital because of sudden right hemiparesis and dysarthria. His cranial MRI showed an area of hyperintensity in left pons on DWI and MRA revealed dilated, elongated and tortuous intracranial artery. We diagnosed as acute phase ischemic stroke and intracranial arterial dolichoectasia (IADE). Intravenous infusion of rt-PA was performed 157 minutes after the onset of symptoms, and his hemiparesis improved. However, he subsequently suffered from cerebral infarction 4 times in 6 months, and we treated him twice with thrombolytic therapy...

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...

BACKGROUND AND PURPOSE: Dolichoectasia of the basilar artery is a characteristic finding of Fabry disease. However, its prevalence, severity, and course have been poorly studied. This study quantitatively evaluated, by MRA, a panel of basilar artery parameters in a large cohort of patients with Fabry disease. MATERIALS AND METHODS: Basilar artery mean diameter, curved length, "origin-to-end" linear distance (linear length), and tortuosity index ([curved length ÷ linear length] - 1) were retrospectively measured on 1...

BACKGROUND AND PURPOSE: Vetebrobasilar dolichoectasia is characterized by arterial elongation, dilation, and tortuosity and leads to high risks of ischemic stroke. Our aim was to investigate the differential susceptibility to elastase-induced vertebrobasilar dolichoectasia induction in 2 different mouse strains. MATERIALS AND METHODS: Elastase (25 mU) was injected into the cisterna magna in C57BL/6J (n = 36) and 129/SvEv (SV129) (n = 36) mice. Control animals were injected with heat-inactivated elastase (n = 12 for each strain)...

BACKGROUND AND PURPOSE: Non-saccular aneurysms of the posterior fossa are an uncommon pathology with no clear treatment strategy. The use of flow-diverting stents (FDS) has had mixed results. We sought to evaluate our experience of FDS for the treatment of this pathology. METHODS: We retrospectively reviewed our database of prospectively collected information for all patients treated only with flow diversion for an unruptured non-saccular aneurysm of the posterior circulation between February 2009 and April 2016...

A 47-year-old male presented with a 2-year history of hemifacial spasm. Magnetic resonance imaging performed showed his tortuous basilar artery with nerve compression, and the patient was treated conservatively with botulinum toxin injections with complete resolution of symptoms. This rare disease was caused by his long history of hypertension, which led to his major basilar artery dolichoectasia.

Vertebrobasilar dolichoectasia (VBD) is a rare dilative arteriopathy defined as elongation or widening of the intracranial vertebral and/or basilar arteries. The prevalence ranges from 0.06% to 5.8%. The majority of VBDs are asymptomatic. Downbeat nystagmus has been reported as a component of an infrequent ocular movement disorder in VBD. Nevertheless, oculopalatal tremor (OPT), delayed sequelae of a brainstem lesion, has never been demonstrated in VBD cases. Synchronized rhythmic involuntary contractions of the soft palate with an ocular pendular nystagmus, predominantly vertical pendular nystagmus, are the hallmark presentation...
