Abstract
|
|
|
|
Most ischemic strokes are caused by large artery atherosclerosis, small vessel occlusive disease, or cardioembolism. However, there are some uncommon causes of stroke as well, especially in young stroke patients. These uncommon causes of stroke require various and complex diagnostic work-ups. However, some of them have characteristic neuroimaging or neurosonologic findings, making the diagnosis much easier. Since finding the exact cause of stroke is very important in determining the therapeutic strategy and predicting the prognosis, clinicians should become familiar with these imaging and sonologic characteristics of uncommon causes of stroke. Recently, many novel imaging techniques have been introduced, but neurosonology is still a simple, widely available, noninvasive, and useful technique. This review will discuss the clinical, neurosonologic, and neuroimaging features of uncommon causes of stroke (cervical artery dissection, Takayasu arteritis, patent foramen ovale-stroke, Moyamoya disease, and sickle cell disease) and review current diagnostic methods.
