Intracranial vertebral and basilar arteries are most commonly involved.
Diagnostic Tests. Hadley [2] was the first one to describe the bone erosion of the cervical vertebra caused by a loop of the vertebral artery in 21 corpses. Transposition of the vertebral arteries seemed impossible due to perforating branches to the medulla. 2, 4 SCI has many causes, often procedurally related, including aortic surgery (most common), vertebral angiography, renal artery embolization, and intra-aortic balloon counterpulsation. changes that are indicative of hemorrhage or cord infarct (Figures

Increased diffusion on the apparent diffusion coefficient (ADC) image without restricted diffusion on diffusion-weighted imaging (DWI) at the left medulla was also depicted ( Figures 3 and 4 ). Bilateral brainstem compression by “kissing vertebral arteries” is extremely rare. 33 year old female with hypertension and received mra results that show mild to moderate vertebral artery stenosis. 15

Since the advent of advanced radiological modalities such as MRI and magnetic resonance angiography (MRA), dissections of cervical arteries are increasingly recognised as a common cause of stroke in young adults. Compression most commonly occurs at the ventrolateral surface of medulla.

The purpose of this study is to report and discuss a rare case of brain stem compression syndrome caused by vertebrobasilar dolichoectasia successfully treated with microvascular decompression repositioning technique and documented by computed tomography angiography (CTA) and magnetic resonance imaging (MRI). Vertebral artery medulla compression syndrome (VAMCS) is a condition of significantly lower prevalence and more severe clinical course. Cranial nerve compression and cerebral ischemia findings are frequently seen in symptomatic patients. that the presence of hemorrhage was associated with a worse
