A 33-year-old man presented with a lateral medullary infarction, vertigo, and nausea. At the time of hospital admission, he had Wallenberg syndrome. Although initial magnetic resonance imaging showed no abnormalities, subsequent diffusion-weighted magnetic resonance imaging showed a high-intensity area in the right lateral medulla oblongata. The right vertebral artery was shown to be dilated on...

We present a case of a ruptured vertebral artery dissecting aneurysm that mimicked a presumed vascular anomaly by CTA (Computerized Tomographic Angiography). A parenchymal arteriovenous malformation (AVM) or a dural arteriovenous fistula (DAVF) at the craniocervical junction can present with a subarachnoid hemorrhage and cannot be differentiated from a vertebral artery dissection by non invasiv...

BACKGROUND Multivessel cervical dissection with cortical sparing is exceptional in clinical practice. CASE PRESENTATION A 55-year-old man presented with acute-onset neck pain with associated sudden onset right-sided hemiparesis and dysphasia after chiropractic manipulation for chronic neck pain. RESULTS AND DISCUSSION Magnetic resonance imaging revealed bilateral internal carotid artery dis...

Vertebral artery is the first branch of subclavian artery. It merges with the same artery of the opposite side to form basilar artery and becomes one of the important source of blood supply to the brain. Variation in the origin of left vertebral artery was found in 65 year old female during magnetic resonance angiography of the neck vessels. It originated from aortic arch and was longer as ...
