What is a dolichoectasia?
Dolichoectasia refers to an enlargement and elongation of the vertebrobasilar artery. Asymptomatic cases of dolichoectasia of vertebral and basilar arteries are not uncommon. However, there are reports suggesting that VBD can implicate in neurologic symptoms, both by compression of the brain stem and cranial nerves or by producing transient ischemic attacks [ 7 ]. According to the authors’ knowledge the isolated symptom of dizziness due to VA compression of the medulla are extremely rare in the literature (Table 1 ). Astonishingly, there were no neurological abnormalities and cranial nerve affections especially in case (1) in spite of severe compression of the medulla. Due to its gradually progressive nature, the course of brainstem compression by VBD is usually slow. Although sometimes the mass effect of VBD can be very serious, the brainstem can gradually tolerate compression without showing obvious clinical symptoms [ 8 ]. In both cases, vertigo and nystagmus are mostly attributed to compression of vestibular nuclei located in the dorsolateral aspect of the medulla; in addition to compression of cisternal component of the 8th cranial nerve in case (2). No MRI evidence of any ischemic effects or brainstem infarction in both cases.
Is medulla oblongata rare?

Can a medulla oblongata be diagnosed?
A stroke in the medulla oblongata can be more difficult to diagnose than other strokes due to vague symptoms, such as dizziness, balance problems, and headaches. Usually, a neurologist can identify a medullary stroke during a physical examination, but if the symptoms are mild, then it might not be very apparent in the early stages.

Stroke of The Medulla
- A stroke of the medulla oblongata interferes with vital nerve messages and can result in a number of serious problems, such as paralysis on one or both sides of the body, double vision and coordination problems.1 A stroke involving the medulla can also interfere with your body's normal breathing and heart function. Some people with a medullary stroke may require the use o…

Recovery
- If you have had a medullary stroke, your recovery depends on the size of your stroke and how quickly you were treated, as well as your own rate of healing. Strokes of the medulla oblongata do not affect the language or thinking areas of the brain, and this can make it easier for you to participate more fully in your rehabilitation therapy.6
