An intriguing unique presentation of middle cerebral artery dolichoectasia with its fusiform aneurysm: A case report

Abstract

Cerebral dolichoectasia is an uncommon angiopathic disorder, which signifies dilatation, elongation, and tortuosity of intracranial arteries, commonly involving the vertebrobasilar arterial system with rare involvement of anterior and middle cerebral arteries. As a consequence of the weakening of vessel walls, altered cerebral hemodynamics, and compression of nearby neural structures, this condition can cause serious clinical symptoms and complications. The majority are isolated cases and are related to various risk factors such as increasing age, metabolic disorders, chronic hypertension, and hereditary diseases affecting the vascular interstitial framework. Computed tomography cerebral angiography is sensitive in the diagnosis and cerebral digital subtraction angiography is considered standard for diagnosing dolichoectasia. We report a rare case of a 55-year-old male patient who was admitted with a history of trauma, with loss of consciousness on presentation. CT brain angiography was performed which was suggestive of dolichoectasia with fusiform aneurysm of the middle cerebral artery, which was confirmed on digital subtraction angiography.
