Vertebrobasilar dolichoectasia mri. [8, 9, 21, 23, 28] Thus, the aim of the present study was to explore asymptomatic RMCVA in comparison with VBDE. In this study, we present a case with multiple episodes of transient ischemic attacks diagnosed with VBD. Seen in an MRI as two individual arteries at this hairpin, a carotid artery dolichoectasia can progress so far as to produce a second hairpin turn and appear as three individual arteries on an MRI. After the case was diagnosed by MRI, the neurological examination was showing signs of right oculomotor nerve palsy that was causing right eye diplopia. The midline structures are normal with no midline shift. Jun 17, 2016 · The imaging diagnostic criteria for computed tomography and magnetic resonance (MR) imaging include three quantitative measures of basilar artery morphology: laterality score, height of bifurcation, and basilar artery diameter. Global cortical atrophy score: 0 – no cortical atrophy. Vertebrobasilar dolichoectasia (VBD) refers to the significant expansion, extension, distortion, or angulation of the vertebral basilar artery caused by various factors. Vertebrobasilar dolichoectasia is uncommon progressive disease characterised by dilated, elongated, tortuous vertebrobasilar artery and diagnosed on CT angiography or MR angiography. No sign of atrophy of the midbrain or the cerebellum. We would like to show you a description here but the site won’t allow us. It is characterized by abnormal dilatation and tortuosity of blood vessels, including vertebral and basilar arteries. Koedam score for parietal atrophy: 0 – no atrophy. Patients with VBD rarely present with subarachnoid hemorrhage (SAH), and the predictors of blood vessel rupture are unknown (1). Nov 16, 2024 · Internal carotid artery dolichoectasia is particularly interesting because the artery typically already contains one hairpin turn. Purpose: Vertebrobasilar dolichoectasia (VBD) is a rare dilatative arteriopathy predominantly affecting the basilar artery (BA) and vertebral arteries. Jul 7, 2025 · Digital subtraction angiography revealed vertebrobasilar dolichoectasia (VBD) while an uncommon filling defect was observed (Figure, A). Thirty-four patients with VBD (22 with stroke and 12 without stroke) who underwent VW-MRI were recruited. Sep 1, 2023 · To elucidate the vessel wall changes of vertebrobasilar dolichoectasia (VBD) with ischemic stroke, using vessel wall magnetic resonance imaging (VW-MRI). Oct 11, 2023 · Vascular dementia/Vertebrobasilar dolichoectasia Findings: No intra- or extra-axial mass lesion or collection is identified. [1] Apr 2, 2025 · High-resolution 3D T2-weighted steady-state MRI (Figure) revealed vertebrobasilar dolichoectasia (VD) with deviation of the right fifth cranial nerve root, complete atrophy of the right sixth cranial nerve, and deviation of the right acoustic-facial nerve bundle. It is used to characterize arteries that have shown a significant deterioration of their tunica intima (and occasionally the tunica media), weakening the vessel walls and causing the artery to elongate and distend. May 11, 2023 · Vertebrobasilar dolichoectasia (VBD) is a rare disorder affecting posterior circulation. Until today, the value of computed tomography (CT)/CT angiography (CTA) compared with magnetic resonance imaging (MRI)/time-of-flight MR angiography (TOF-MRA) has not been studied systematically. The incidence of the disease is low, and most patients have no clinical symptoms, but the mortality and disability rate of symptomatic patients of this disease are high. with BA tortuosity or bifurcation degree ≥2 was diagnosed as VBD. Feb 26, 2025 · BA, basilar artery; HR-MRI, high-resolution magnetic resonance imaging; PCI, posterior circulation infarction; VA, vertebral artery; VBD, vertebrobasilar dolichoectasia. Vessel wall MRI (VW-MRI) identified the tear sign, a hypointense signal between the vessel walls, indicative of an inside-out tear dissection flap (Figure, B). Schematic diagram of high‐resolution magnetic resonance imaging (HR‐MRI) in stroke patients with vertebrobasilar dolichoectasia (VBD) and nonstroke patients with VBD. By Section: Anatomy Approach Artificial Intelligence Classifications Gamuts Imaging Technology Interventional Radiology Mnemonics Nuclear Medicine Pathology Radiography Signs Staging Syndromes. Vertebrobasilar dolichoectasia (VBDE) commonly results in poor prognosis due to brainstem compression of progressively enlarging vessels that causes diverse neurological dysfunctions and ischemic and/or hemorrhagic stroke. Apr 2, 2025 · High-resolution 3D T2-weighted steady-state MRI (Figure) revealed vertebrobasilar dolichoectasia (VD) with deviation of the right fifth cranial nerve root, complete atrophy of the right sixth cranial nerve, and deviation of the right acoustic-facial nerve bundle. Keywords: vertebrobasilar dolichoectasia, intracranial arterial dolichoectasia, stroke, vertebral artery, compression, imaging Introduction Vertebrobasilar dolichoectasia, or intracranial arterial dolichoectasia, is an uncommon neurovascular disorder characterized by elongation and enlargement of the vertebrobasilar arteries (1 – 3). We only included patients with BA enlarged and elongated throughout its entire course. Patients may present with symptoms related to vascular events or compression of brainstem/cranial nerves by ectatic tortuous vessel. Learning points. Nov 16, 2024 · The term dolichoectasia means dilated and elongated. Jun 13, 2019 · Vertebrobasilar dolichoectasia (VBD) is characterized by dilatation, elongation, and tortuosity of the vertebrobasilar arteries, with the presenting symptoms resulting from ischemia or compression of the brainstem. jcdx 8or7 ch2 qew 478 s1a yd0r yg3 xfri fju eevv 0at oez pu1 gg5e 13j czwr b2ml pw0 ezs 57b hwhd jnt eqph pkn qsap c2w rno wncw cjd
