Relation of infarction location and volume to vertigo in vertebrobasilar stroke

ConclusionInfarction location in the cerebellum and/or dorsal brainstem is an independent predictor of vertigo. Furthermore, larger infarction volume in these structures is associated with vertigo. A considerable proportion of patients with vascular vertigo present without focal neurological deficits posing a diagnostic challenge. National Institute of Health Stroke Scale is not sensitive for vertebrobasilar stroke.

We report a 42-year old men who presented to our observation with acute tongue swelling and atrophy of left side of tongue from a hypoglossal nerve injury. A magnetic resonance imaging revealed a denervation of the left half of the tongue from a hypoglossal nerve injury due to left extracranial internal carotid artery (ICA) dissection, without evidence of ischemic stroke. The urine toxicology screen test revealed a positivity for cocaine. This case report suggest to perform in young patient a toxicological drug screening test in presence of ICA dissection with hypoglossal nerve injury and an acute tongue swelling. However ...

This study is a prospective clinical study. Purpose: This study aims to evaluate the characteristics of trunk musculature and intervertebral discs by using magnetic resonance imaging in patients with spinal cord injuries (SCIs) with thoracic and lumbar fractures. Overview of Literature: Muscle atrophy is an immediate consequence of SCI and is associated with secondary complications. At present, there are limited clinical data on muscle and disc responses to fractures of the thoracic and lumbar spine. Methods: A total of 51 patients with a mean age of 31.75±10.42 years who suffered traumatic SCI were incl...

Authors: Ogon I, Takashima H, Morita T, Oshigiri T, Terashima Y, Yoshimoto M, Fukushi R, Fujimoto S, Emori M, Teramoto A, Takebayashi T, Yamashita T Abstract Study Design: Cross-sectional study. Purpose: The purpose of this study was to elucidate the relevance among Schmorl's node (SN), chronic low back pain (CLBP), and intervertebral disc degeneration (IVDD) with the use of magnetic resonance imaging T2 mapping. Overview of Literature: SN may be combined with CLBP and/or IVDD; however, their relationship has not been determined to date. Methods: A total of 105 subjects were included (48 men and 57 wome...

We report the case of a 63-year-old man with multiple atherosclerotic risk factors and atrial fibrillation who showed repeated episodes of isolated vertigo. His repeated vertigo was short-lasting and was often triggered by body position, mimicking benign paroxysmal positional vertigo.

ConclusionEmergency department patients with symptoms of vertigo or dizziness had sevenfold higher risk of acute cerebrovascular syndromes than the general population. Atrial fibrillation and diabetes mellitus are risk factors associated with high risk of acute cerebrovascular syndromes in these patients.

Cerebellar strokes account for less than 10% of all strokes but lead to significantly poor outcomes. Cerebellar strokes that are initially missed have a mortality rate of 40%, and half of the patients who survive have long-term deficits. The patient's history may provide clues that point to a cerebellar stroke. Signs and symptoms include vertigo, headache, vomiting and ataxia. It is important to note the presence of stroke risk factors, such as a history of strokes or transient ischemic attacks, diabetes mellitus, hypertension, hypercholesterolemia, advanced age, atrial fibrillation, and cigarette smoking. The importance o...

We present 2 cases in the setting of acute vertebrobasilar territory ischaemia. Case 1: A 56-year old man was admitted with acute dyspnoea and new atrial fibrillation. On day two while lying in bed, he developed vomiting and suddenly perceived the curtain to his left was lying horizontal along the floor and felt he was sliding towards the left. MRI brain revealed acute multiterritory infarction (Figure 1). He was commenced on therapeutic anticoagulation and was well on follow-up. Case 2: A 47-year old man awoke with acute vertigo, vomiting and ataxia, exacerbated by head movement with dysarthria and diplopia. The worl...

Conclusions: Cerebral infarcts due to CM in immunocompetent patients are unusual. However, cryptococcal infection should be considered in atypical stroke manifestations, since early diagnosis and prompt treatment can improve outcome.Disclosure: Dr. Khattak has nothing to disclose.
