PURPOSE To assess the prevalence of vertebral artery dissection in Wallenberg syndrome. METHODS Sixteen patients (12 men, 4 women; mean age at ictus, 51.6 years) with symptoms of Wallenberg syndrome and an infarction demonstrated in the lateral medulla on MR were reviewed retrospectively. The study items were as follows: (a) headache as clinical signs, in particular, occipitalgia and/or poste...

We report three patients who developed delayed (ie, more than a week after the injury) symptoms of vertebrobasilar ischemia following motor vehicle accidents. The patients all had angiographic evidence of vertebral artery dissection and, upon further evaluation, occult fractures of the second cervical vertebra that were not detected by simple cervical spine radiography and required polytomograp...

Background Turner syndrome is associated with bicuspid aortic valve (BAV), coarctation of the aorta, aortic dilation, and aortic dissection. Vertebral artery tortuosity, as demonstrated by magnetic resonance angiography (MRA), is increased in other disorders associated with thoracic aortic dilation and dissection, including Marfan syndrome and Loeys-Dietz syndrome, and increased tortuosity is a...

Clinical and radiologic findings in 13 patients (11 women, 2 men) with extracranial vertebral artery dissection are reported. Dissection was spontaneous in 8 patients, occurred after neck manipulation in 2 and after a potential minor injury to the neck in 3. Six had a history of common migraine, 4 were using oral contraceptives at the time of dissection, and 3 had fibromuscular dysplasia. Disse...

We found a case of hypoplasia of vertebral artery with fibromuscular dysplasia in an 82-yr-old Korean female cadaver during a routine dissection course. In the present case, intracranial hypoplasia in left vertebral artery and bilateral origin of posterior inferior cerebellar artery at the vertebrobasilar junction were recognized. Histopathologically, left vertebral artery showed intimal type o...

Dissection of the vertebral artery is an important but rare cause of cerebrovascular accidents. Here we report a 48-year-old man with toothache since 4 days before who presented to the emergency department with neck pain and final diagnosis of dissecting right vertebral artery pseudoaneurysm. To our knowledge, this maybe the first report of odontogenic pain as the first manifestation of vertebr...

BACKGROUND Neurologic deficits in patients with Klippel-Feil syndrome usually are attributed to direct compression of neuronal structures or hypoperfusion secondary to compression of the vertebral arteries by bony abnormalities. OBJECTIVE To describe a 38-year-old woman with known Klippel-Feil syndrome who developed lateropulsion. RESULTS The results of magnetic resonance imaging were consi...

BACKGROUND Spontaneous coronary and vertebral artery dissections are rare events occurring most commonly in otherwise healthy women during pregnancy or the post-partum period. CASE PRESENTATION This report describes a 35-year-old female who presented with an acute inferior ST elevation myocardial infarction 7 months post-partum secondary to spontaneous dissection of the left obtuse marginal c...
