Wegener's Granulomatosis Presenting as Wallenberg Syndrome: A Case Report
Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, a vasculitis affecting small and medium sized vessels usually affects the upper and lower respiratory tract, the kidneys, and the eyes. Neurologic manifestation in central nervous system (CNS) is less frequent than the peripheral and usually is in form of stroke. Few cases of lateral medullary ischemic stroke (Wallenberg syndrome) due to GPA have been reported. A 41 year-old female, presented with acute vertigo, nausea/vomiting, hiccups, dysphagia.

Discovery of a New Biomarker Pattern for Differential Diagnosis of Acute Ischemic Stroke Using Targeted Metabolomics
Stroke is one of the leading causes of disability all over the world. However, biomarkers for fast differential diagnosis of acute ischemic stroke (AIS) from vertigo or headache, remains lacking. Using a direct-infusion mass spectrometry method, it is possible to establish an efficient method for AIS differential diagnosis that requires only a few minutes. Thirty-eight clearly diagnosed AIS patients and 46 patients with a main complaint of vertigo were enrolled in this study. There was a total of 58 metabolites that were measured by our targeted metabolomics method, and the data were analyzed by pattern recognition algorit...

Posterior Circulation Ischaemic Stroke
Am J Med Sci. 2022 Jan 29:S0002-9629(22)00030-1. doi: 10.1016/j.amjms.2021.10.027. Online ahead of print.ABSTRACTPosterior circulation ischaemic stroke (PCIS) is a disease of high burden. They account for 20-25% of all ischaemic strokes. However, it is relatively under-researched and requires more clinical attention, since it carries worse functional outcomes. Vertigo, visual disturbances and sensory/motor disturbances are found in PCIS. Large artery atherosclerosis and embolism are main causes of PCIS, while there is growing evidence that vertebrobasilar dolichoectasia is a key association. Hypertension is the commonest r...

Posterior circulation stroke due to intracranial artery disease in the Chinese population
ConclusionsPCS due to INVAD was more common in the Chinese population. However, PCS due to IVAD had more serious clinical-radiologic patterns and worse outcomes.

Craniovertebral Junction Anomalies: An Overlooked Cause of & #39;Posterior Circulation Stroke & #39;
Conclusions: CVJ anomalies can present as posterior circulation infarct. One must evaluate all patients with posterior circulation stroke, especially young patients, for possible CVJ anomalies. Dynamic lateral cervical spine X-ray is an important tool to diagnose AAD. CVJ anomalies represent a treatable cause of VAD.

Transient neurological attack before vertebrobasilar stroke
Abstract: Background: Patients with vertebrobasilar (VB) circulation ischemia can present with nonspecific symptoms, which complicate the distinction of transient ischemic attack (TIA) from other benign disorders. According to previously accepted classifications, typical TIA does not occur with VB symptom such as vertigo, diplopia, or dysarthria in isolation. However, there is a lack of evidence to support this hypothesis.Methods: This hospital-based study included 214 consecutive patients with acute ischemic VB stroke. We defined transient neurological attacks (TNAs) as temporary (

Rotational Vertebral Artery Occlusion: Mechanisms and Long-term Outcome Clinical Sciences
Conclusions— RVAO has various patterns of vertebral artery compression, and favorable long-term outcome with conservative treatments. In most patients with RVAO, the symptoms may be ascribed to asymmetrical excitation of the bilateral labyrinth induced by transient ischemia or by disinhibition from inferior cerebellar hypoperfusion. Conservative management might be considered as the first-line treatment of RVAO.

Gravity-dependent Nystagmus and Inner-Ear Dysfunction Suggest Anterior and Posterior Inferior Cerebellar Artery Infarct
Cerebellar lesions may present with gravity-dependent nystagmus, where the direction and velocity of the drifts change with alterations in head position. Two patients had acute onset of hearing loss, vertigo, oscillopsia, nausea, and vomiting. Examination revealed gravity-dependent nystagmus, unilateral hypoactive vestibulo-ocular reflex (VOR), and hearing loss ipsilateral to the VOR hypofunction. Traditionally, the hypoactive VOR and hearing loss suggest inner-ear dysfunction. Vertigo, nausea, vomiting, and nystagmus may suggest peripheral or central vestibulopathy. The gravity-dependent modulation of nystagmus, however, ...

Stroke of luck
Wes Varda recalls noticing symptoms of what would result in a stroke a year before it actually happened. In 2007, he began feeling dizzy, and it would get worse with seasonal allergies. After a really bad episode that sent him home from work, he consulted his doctor who diagnosed it as benign vertigo. A year later, Varda had another dizzy spell, but this time, he lost voluntary control of his muscles. Realizing something was wrong, he called his father for help, and a few hours later, Varda’s…

How Commonly Is Stroke Found in Patients with Isolated Vertigo or Dizziness Attack?
The sudden development of vertigo or dizziness without focal neurological symptoms is generally attributable to vestibular diseases such as benign paroxysmal positional vertigo. Isolated vertigo or dizziness attack needs more attention than vestibular diseases. This retrospective study was performed to elucidate the frequency of strokes in patients with isolated vertigo or dizziness attack.

Clinical Presentation, Magnetic Resonance Angiography, Ultrasound Findings, and Stroke Patterns in Patients with Vertebral Artery Dissection
Background/Aims: Vertebral artery dissection (VAD) is an important cause of ischemic stroke. In this observational study, clinical data, magnetic resonance (MR) and ultrasound (US) imaging findings and ischemic patterns were analyzed.Methods: Forty-seven patients with a diagnosis of VAD underwent clinical examination, US, MR of the brain and neck and MR angiography (MRA) of the cervical arteries. Vascular abnormalities and ischemic brain lesions were noted. Data were evaluated separately and compared for spontaneous and traumatic VAD subgroups.Results: The most common overall clinical symptom was vertigo followed by neck p...
