Cerebral ischemia because of vertebrobasilar insufficiency (VBI) rarely presents as an initial sign within the systemic lupus erythematosus (SLE) population, and there are very few case reports supporting this manifestation. This report details 3 different patients with SLE who experienced VBI as an initial manifestation. Patient 1 was a 24-year-old female who developed a bilateral pontine lesion as a consequence of basilar artery stenosis. Patient 2 was a 34-year-old male with an acute ischemic lesion on the right side of his cerebellum and pons because of significant stenosis in the distal segment of the right vertebral artery...

We evaluated the role of vertebral artery extracranial color-coded duplex sonography (VAECCS) in predicting vertebrobasilar stroke in consecutive patients presenting to the emergency department with vertigo of suspected ischemic origin. The final diagnosis was established by a panel of experts consisting of an emergency physician, a neurologist, and an otoneurologist. Vertebrobasilar stroke was diagnosed when an acute brain ischemic lesion congruent with symptoms was detected by neuroimaging during the index visit or a stroke was diagnosed within a 3-mo period after emergency department presentation...

A significant number of patients who seek medical treatment in an emergency department because of vertigo or dizziness, suffer from acute vestibular syndrome. This is characterized by sustained vertigo, horizontal or horizontal rotatory jerk nystagmus, and unsteady stance and gait. In the acute situation it is crucial to differentiate patients with a peripheral vestibular disorder from those with a central disease. A number of recent studies have shown that a structured clinical examination enables a reliable differential diagnosis of central or peripheral disorders...

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...

Diagnosis of traumatic subarachnoid hemorrhage (SAH), although relatively rare, is important in forensic medicine. It is mostly associated with rupture of the vertebrobasilar artery. Traumatic aneurysm of the intracranial part of the internal carotid artery (ICA) is also rare but has been reported in several studies. It is thought that the intracranial ICA is injured by blunt force to the head, neck, and chest. However, traumatic SAH with fatal acute course resulting from rupture of the ICA is especially uncommon: only two fatal cases without an associated aneurysm have been reported in the English-language literature...

OBJECTIVES: Patients with posterior circulation infarction are at higher risk of early recurrent stroke, especially those with vertebrobasilar stenosis or hypoplasia. The clinical presentations of this condition vary over a broad range, making diagnosis and treatment a challenge. Hemodynamic changes and stenosis detected by ultrasonography (US) are sensitive and important indicators for further evaluation. In this study, we correlated extracranial and intracranial US characteristics with brain magnetic resonance imaging (MRI) in patients with posterior circulation infarction...

BACKGROUND: Subclinical atrial fibrillation is one possible cause of embolic stroke of undetermined source (ESUS). It remains to be elucidated if a specific infarction site has a predictive value for detecting subclinical atrial fibrillation. We aimed to investigate the predictive value of infarction site in patients with ESUS for the detection of atrial tachyarrhythmia (AT) using an insertable cardiac monitor. METHODS AND RESULTS: Consecutive 146 patients (84 men; aged 62±12 years) underwent insertable cardiac monitor implantation after diagnosis of ESUS...

The persistent primitive hypoglossal artery (PPHA) is the second most common persistent carotid-vertebrobasilar anastomosis. We present a rare case of an 82-year-old woman who diagnosed as acute cerebral infarction three times in both the anterior and posterior circulation territories with a right-sided PPHA and ipsilateral carotid artery dissection (CAD). Microembolus monitoring results suggested that microembolic caused by CAD associated with PPHA should be recognized as a possible cause of multiple infarctions in both the anterior and posterior circulation territories...
