Excerpt
Middle cerebral artery (MCA) dissection is an uncommon cause of stroke. Despite its low incidence, MCA dissection has drawn attention as an important cause of stroke in young people. The clinical presentation of MCA dissection is not specific. Capsular warning syndrome (CWS), which is a manifestation of MCA dissection, has only rarely been reported [

3]. One Chinese patient was evidenced using high-resolution magnetic resonance imaging (HR-MRI), and a Latin American patient was evidenced using digital subtraction angiography (DSA) [

3]. Both patients received dual antiplatelet therapy, and symptoms did not recur. However, no follow-up images were available. A previous follow-up study found that most patients with intracranial arterial dissection completed the vascular repair within 2 months, but there were also a few dissection lesions that showed bleeding or progression [
4]. Therefore, in addition to obtaining clinical outcomes, the evaluation of imaging prognosis after treatment is essential. We used HR-MRI to diagnose and follow up a case of middle cerebral artery dissection presenting with CWS. …
