abstract in English:	Background: Dolichoectasia of intracranial arteries is a rare arteriopathy characterized by elongation and widening of the arteries and disturbance of the laminar blood flow. It involves mostly vertebral and basilar arteries. In advanced cases, formation of a fusiform aneurysm is possible. Case Report: A sixty-four-year-old female with hypertension was admitted to the hospital with severe nonsystemic vertigo and dysarthria, which had lasted for a couple of weeks. Imaging of the brain revealed dolichoectasia of arteries of the circle of Willis coexisting with a fusiform aneurysm of the basilar artery. Conclusions: Intracranial arterial dolichoectasia may be asymptomatic for a long time. However, in many cases it leads to neurological symptoms associated with haemodynamic disturbance (due to unstable wall clots) and mass effect caused by the widened vessel.
