Application of transcranial Doppler sonography in children with acute neurologic events due to primary cerebral and West Nile vasculitis

ler studies to evaluate neurovascular disease in three girls presenting with acute stroke due to primary cerebral vas-culitis (n 2) and West Nile vasculitis (n 1). Correlation of abnormal findings on transcranial Doppler sonography was compared with those of MR angiography and conven-tional angiography in each child. All three girls had left middle cerebral artery infarcts on MR imaging, with an abnormal left middle cerebral artery detected by MR an-giography, conventional angiography, and transcranial Doppler sonography in each child. In all three cases, find-ings of the transcranial Doppler sonography, MR imaging, and catheter angiography were concordant. The use of transcranial Doppler sonography is well established in the evaluation of many neurovascular conditions ranging from sickle cell vasculopathy t
