The latter is a branch of the vertebral artery, that is the. Conclusion: In the early stage of vertebrobasilar stroke, an accurate diagnosis was difficult in the Emergency Department even though a radiologic study was performed, but various VNG abnormalities and delayed neurologic signs could help to diagnose whether the origin is central or not. The PICAstroke syndrome is also known as 'lateral medullary syndrome', or 'Wallenbergs syndrome', after Wallenbergs description in 1895. key words: Lateral Medullary Syndrome, dysphagia, nystagmus, symptomatic therapy. Stroke occurred in the cerebellum (n = 18, 78%), medulla (n = 4, 17%), and pons (n = 1, 4%). Wallenberg Syndrome Symptoms: hoarseness, n/v, hiccups, nystagmus. In the analysis of VNG, 11 (48%) cases of direction-changing gaze-evoked nystagmus, 7 (30%) cases of fixation failure in the caloric test, 6 (27%) cases of periodic alternating nystagmus, and 4 (17%) cases of atypical head-shaking nystagmus were presented. Dorsal lateral medullary syndrome PICA strokes that spare the medulla Isolated. Of the 23 patients, 17 (74%) showed aggravation of vertigo or delayed neurologic signs during the admission. Results: Of the 468 cases of acute vestibular syndrome, 23 (4.9%) cases of radiologically proven vertebrobasilar stroke were identified. Various clinical features, including presenting symptoms, delayed neurologic signs, the site of infarction, and videonystagmographic (VNG) findings were analyzed. 102, 103 Most often this disorder is due to ischemia in the distribution of the posterior inferior cerebellar artery (PICA). Clinical symptoms include swallowing difficulty, or dysphagia 1, slurred speech, ataxia, facial pain, vertigo, nystagmus, Horners syndrome, diplopia. Lateral medullary syndrome, also known as Wallenberg syndrome, is a clinical syndrome caused by an acute ischemic infarct of the lateral medulla oblongata. They were referred to the Otolaryngology Department due to the absence of neurologic signs or even of imaging abnormalities after the initial examination at the Emergency Department. Probably the most easily recognized central vestibular disorder is that of Wallenberg syndrome, which is caused by infarction of the lateral medulla (which includes the vestibular nuclei). Methods: The patients who presented with isolated acute spontaneous vertigo with spontaneous nystagmus (acute vestibular syndrome) at the Emergency Department were retrospectively analyzed. Background: We aimed to investigate the clinical courses and common nystagmus of isolated vertigo patients with vertebrobasilar stroke.
