Middle cerebral artery dolichoectasia with radiologic follow-up.

Intracranial dolichoectasia is an angiopathy characterized by dilation, elongation, and tortuosity of the cerebral arteries. It most frequently involves the vertebrobasilar arteries and carotid arteries, whereas a more peripheral location involving the anterior and the middle cerebral arteries (MCAs) is less frequent. We present a male patient with MCA dolichoectasia with radiologic follow-up for 3 years, and no ischemia or intracranial bleeding occurred after the antiplatelet therapy. From the reported case series of MCA dolichoectasia, we suggest that surgical procedure should not be adopted unless accompanied by aneurysm located at dolichoectatic MCA. Moreover, anticoagulation or antiplatelet therapy could be a good treatment of option to prevent ischemic events.
