Extensive intracranial arterial dolichoectasia involving distal branches of intracranial arteries: two cases report and review of the literature

Abstract

With the rapid development of noninvasive angiography techniques such as Magnetic Resonance Angiography (MRA) and Computer Tomography Angiography (CTA), more and more patients with intracranial arterial dolichoectasia (IADE) have been found, and clinical studies on this kind of vascular abnormity have become hot subjects in neurology. We presented two young patients with IADE extensively involving the branches of intracranial arteries, which were different from patients described in other articles. A young male patient was diagnosed with IADE after examination on admission, and further detailed examination revealed that the patient had osteropathia striata. Another young woman had an arterial malformation that mainly affected the distal branch of the intracranial artery. These two cases give us another perspective to look into IADE.
